cmake version 2.6-patch 2
------------------------------------------------------------------------------
Name

  cmake - Cross-Platform Makefile Generator.

------------------------------------------------------------------------------
Usage

  cmake [options] <path-to-source>
  cmake [options] <path-to-existing-build>

------------------------------------------------------------------------------
Description

The "cmake" executable is the CMake command-line interface.  It may be used
to configure projects in scripts.  Project configuration settings may be
specified on the command line with the -D option.  The -i option will cause
cmake to interactively prompt for such settings.

CMake is a cross-platform build system generator.  Projects specify their
build process with platform-independent CMake listfiles included in each
directory of a source tree with the name CMakeLists.txt.  Users build a
project by using CMake to generate a build system for a native tool on their
platform.

------------------------------------------------------------------------------
Options

  -C <initial-cache>
       Pre-load a script to populate the cache.

       When cmake is first run in an empty build tree, it creates a
       CMakeCache.txt file and populates it with customizable settings for
       the project.  This option may be used to specify a file from which to
       load cache entries before the first pass through the project's cmake
       listfiles.  The loaded entries take priority over the project's
       default values.  The given file should be a CMake script containing
       SET commands that use the CACHE option, not a cache-format file.

  -D <var>:<type>=<value>
       Create a cmake cache entry.

       When cmake is first run in an empty build tree, it creates a
       CMakeCache.txt file and populates it with customizable settings for
       the project.  This option may be used to specify a setting that takes
       priority over the project's default value.  The option may be repeated
       for as many cache entries as desired.

  -U <globbing_expr>
       Remove matching entries from CMake cache.

       This option may be used to remove one or more variables from the
       CMakeCache.txt file, globbing expressions using * and ? are supported.
       The option may be repeated for as many cache entries as desired.

       Use with care, you can make your CMakeCache.txt non-working.

  -G <generator-name>
       Specify a makefile generator.

       CMake may support multiple native build systems on certain platforms.
       A makefile generator is responsible for generating a particular build
       system.  Possible generator names are specified in the Generators
       section.

  -Wno-dev
       Suppress developer warnings.

       Suppress warnings that are meant for the author of the CMakeLists.txt
       files.

  -Wdev
       Enable developer warnings.

       Enable warnings that are meant for the author of the CMakeLists.txt
       files.

  -E
       CMake command mode.

       For true platform independence, CMake provides a list of commands that
       can be used on all systems.  Run with -E help for the usage
       information.

  -i
       Run in wizard mode.

       Wizard mode runs cmake interactively without a GUI.  The user is
       prompted to answer questions about the project configuration.  The
       answers are used to set cmake cache values.

  -L[A][H]
       List non-advanced cached variables.

       List cache variables will run CMake and list all the variables from
       the CMake cache that are not marked as INTERNAL or ADVANCED.  This
       will effectively display current CMake settings, which can be then
       changed with -D option.  Changing some of the variable may result in
       more variables being created.  If A is specified, then it will display
       also advanced variables.  If H is specified, it will also display help
       for each variable.

  -N
       View mode only.

       Only load the cache.  Do not actually run configure and generate
       steps.

  -P <file>
       Process script mode.

       Process the given cmake file as a script written in the CMake
       language.  No configure or generate step is performed and the cache is
       not modified.  If variables are defined using -D, this must be done
       before the -P argument.

  --graphviz=[file]
       Generate graphviz of dependencies.

       Generate a graphviz input file that will contain all the library and
       executable dependencies in the project.

  --system-information [file]
       Dump information about this system.

       Dump a wide range of information about the current system.  If run
       from the top of a binary tree for a CMake project it will dump
       additional information such as the cache, log files etc.

  --debug-trycompile
       Do not delete the try compile directories..

       Do not delete the files and directories created for try_compile calls.
       This is useful in debugging failed try_compiles.

  --debug-output

Generators

The following generators are available on this platform:

  Unix Makefiles
       Generates standard UNIX makefiles.

       A hierarchy of UNIX makefiles is generated into the build tree.  Any
       standard UNIX-style make program can build the project through the
       default make target.  A "make install" target is also provided.

  CodeBlocks - Unix Makefiles
       Generates CodeBlocks project files.

       Project files for CodeBlocks will be created in the top directory and
       in every subdirectory which features a CMakeLists.txt file containing
       a PROJECT() call.  Additionally a hierarchy of makefiles is generated
       into the build tree.  The appropriate make program can build the
       project through the default make target.  A "make install" target is
       also provided.

  Eclipse CDT4 - Unix Makefiles
       Generates Eclipse CDT 4.0 project files.

       Project files for Eclipse will be created in the top directory and
       will have a linked resource to every subdirectory which features a
       CMakeLists.txt file containing a PROJECT() call.Additionally a
       hierarchy of makefiles is generated into the build tree.  The
       appropriate make program can build the project through the default
       make target.  A "make install" target is also provided.

  KDevelop3
       Generates KDevelop 3 project files.

       Project files for KDevelop 3 will be created in the top directory and
       in every subdirectory which features a CMakeLists.txt file containing
       a PROJECT() call.  If you change the settings using KDevelop cmake
       will try its best to keep your changes when regenerating the project
       files.  Additionally a hierarchy of UNIX makefiles is generated into
       the build tree.  Any standard UNIX-style make program can build the
       project through the default make target.  A "make install" target is
       also provided.

  KDevelop3 - Unix Makefiles
       Generates KDevelop 3 project files.

------------------------------------------------------------------------------
Commands

  add_custom_command
       Add a custom build rule to the generated build system.

       There are two main signatures for add_custom_command The first
       signature is for adding a custom command to produce an output.

         add_custom_command(OUTPUT output1 [output2 ...]
                            COMMAND command1 [ARGS] [args1...]
                            [COMMAND command2 [ARGS] [args2...] ...]
                            [MAIN_DEPENDENCY depend]
                            [DEPENDS [depends...]]
                            [IMPLICIT_DEPENDS <lang1> depend1 ...]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM] [APPEND])

       This defines a new command that can be executed during the build
       process.  The outputs named should be listed as source files in the
       target for which they are to be generated.  If an output name is a
       relative path it will be interpreted relative to the build tree
       directory corresponding to the current source directory.  Note that
       MAIN_DEPENDENCY is completely optional and is used as a suggestion to
       visual studio about where to hang the custom command.  In makefile
       terms this creates a new target in the following form:

         OUTPUT: MAIN_DEPENDENCY DEPENDS
                 COMMAND

       If more than one command is specified they will be executed in order.
       The optional ARGS argument is for backward compatibility and will be
       ignored.

       The second signature adds a custom command to a target such as a
       library or executable.  This is useful for performing an operation
       before or after building the target.  The command becomes part of the
       target and will only execute when the target itself is built.  If the
       target is already built, the command will not execute.

         add_custom_command(TARGET target
                            PRE_BUILD | PRE_LINK | POST_BUILD
                            COMMAND command1 [ARGS] [args1...]
                            [COMMAND command2 [ARGS] [args2...] ...]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM])

       This defines a new command that will be associated with building the
       specified target.  When the command will happen is determined by which
       of the following is specified:

         PRE_BUILD - run before all other dependencies
         PRE_LINK - run after other dependencies
         POST_BUILD - run after the target has been built

       Note that the PRE_BUILD option is only supported on Visual Studio 7 or
       later.  For all other generators PRE_BUILD will be treated as
       PRE_LINK.

       If WORKING_DIRECTORY is specified the command will be executed in the
       directory given.  If COMMENT is set, the value will be displayed as a
       message before the commands are executed at build time.  If APPEND is
       specified the COMMAND and DEPENDS option values are appended to the
       custom command for the first output specified.  There must have
       already been a previous call to this command with the same output.
       The COMMENT, WORKING_DIRECTORY, and MAIN_DEPENDENCY options are
       currently ignored when APPEND is given, but may be used in the future.

       If VERBATIM is given then all the arguments to the commands will be
       passed exactly as specified no matter the build tool used.  Note that
       one level of escapes is still used by the CMake language processor
       before ADD_CUSTOM_TARGET even sees the arguments.  Use of VERBATIM is
       recommended as it enables correct behavior.  When VERBATIM is not
       given the behavior is platform specific.  In the future VERBATIM may
       be enabled by default.  The only reason it is an option is to preserve
       compatibility with older CMake code.

       If the output of the custom command is not actually created as a file
       on disk it should be marked as SYMBOLIC with
       SET_SOURCE_FILES_PROPERTIES.

       The IMPLICIT_DEPENDS option requests scanning of implicit dependencies
       of an input file.  The language given specifies the programming
       language whose corresponding dependency scanner should be used.
       Currently only C and CXX language scanners are supported.
       Dependencies discovered from the scanning are added to those of the
       custom command at build time.  Note that the IMPLICIT_DEPENDS option
       is currently supported only for Makefile generators and will be
       ignored by other generators.

       If COMMAND specifies an executable target (created by ADD_EXECUTABLE)
       it will automatically be replaced by the location of the executable
       created at build time.  Additionally a target-level dependency will be
       added so that the executable target will be built before any target
       using this custom command.  However this does NOT add a file-level
       dependency that would cause the custom command to re-run whenever the
       executable is recompiled.

       If DEPENDS specifies any target (created by an ADD_* command) a
       target-level dependency is created to make sure the target is built
       before any target using this custom command.  Additionally, if the
       target is an executable or library a file-level dependency is created
       to cause the custom command to re-run whenever the target is
       recompiled.


  add_custom_target
       Add a target with no output so it will always be built.

         add_custom_target(Name [ALL] [command1 [args1...]]
                           [COMMAND command2 [args2...] ...]
                           [DEPENDS depend depend depend ... ]
                           [WORKING_DIRECTORY dir]
                           [COMMENT comment] [VERBATIM])

       Adds a target with the given name that executes the given commands.
       The target has no output file and is ALWAYS CONSIDERED OUT OF DATE
       even if the commands try to create a file with the name of the target.
       Use ADD_CUSTOM_COMMAND to generate a file with dependencies.  By
       default nothing depends on the custom target.  Use ADD_DEPENDENCIES to
       add dependencies to or from other targets.  If the ALL option is
       specified it indicates that this target should be added to the default
       build target so that it will be run every time (the command cannot be
       called ALL).  The command and arguments are optional and if not
       specified an empty target will be created.  If WORKING_DIRECTORY is
       set, then the command will be run in that directory.  If COMMENT is
       set, the value will be displayed as a message before the commands are
       executed at build time.  Dependencies listed with the DEPENDS argument
       may reference files and outputs of custom commands created with
       ADD_CUSTOM_COMMAND.

       If VERBATIM is given then all the arguments to the commands will be
       passed exactly as specified no matter the build tool used.  Note that
       one level of escapes is still used by the CMake language processor
       before add_custom_target even sees the arguments.  Use of VERBATIM is
       recommended as it enables correct behavior.  When VERBATIM is not
       given the behavior is platform specific.  In the future VERBATIM may
       be enabled by default.  The only reason it is an option is to preserve
       compatibility with older CMake code.

  add_definitions
       Adds -D define flags to the compilation of source files.

         add_definitions(-DFOO -DBAR ...)

       Adds flags to the compiler command line for sources in the current
       directory and below.  This command can be used to add any flags, but
       it was originally intended to add preprocessor definitions.  Flags
       beginning in -D or /D that look like preprocessor definitions are
       automatically added to the COMPILE_DEFINITIONS property for the
       current directory.  Definitions with non-trival values may be left in
       the set of flags instead of being converted for reasons of backwards
       compatibility.  See documentation of the directory, target, and source
       file COMPILE_DEFINITIONS properties for details on adding preprocessor
       definitions to specific scopes and configurations.

  add_dependencies
       Add a dependency between top-level targets.

         add_dependencies(target-name depend-target1
                          depend-target2 ...)

       Make a top-level target depend on other top-level targets.  A
       top-level target is one created by ADD_EXECUTABLE, ADD_LIBRARY, or
       ADD_CUSTOM_TARGET.  Adding dependencies with this command can be used
       to make sure one target is built before another target.  See the
       DEPENDS option of ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND for adding
       file-level dependencies in custom rules.  See the OBJECT_DEPENDS
       option in SET_SOURCE_FILES_PROPERTIES to add file-level dependencies
       to object files.

  add_executable
       Add an executable to the project using the specified source files.

         add_executable(<name> [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL]
                        source1 source2 ... sourceN)

       Adds an executable target called <name> to be built from the source
       files listed in the command invocation.  The <name> corresponds to the
       logical target name and must be globally unique within a project.  The
       actual file name of the executable built is constructed based on
       conventions of the native platform (such as <name>.exe or just
       <name>).

       By default the executable file will be created in the build tree
       directory corresponding to the source tree directory in which the
       command was invoked.  See documentation of the
       RUNTIME_OUTPUT_DIRECTORY target property to change this location.  See
       documentation of the OUTPUT_NAME target property to change the <name>
       part of the final file name.

       If WIN32 is given the property WIN32_EXECUTABLE will be set on the
       target created.  See documentation of that target property for
       details.

       If MACOSX_BUNDLE is given the corresponding property will be set on
       the created target.  See documentation of the MACOSX_BUNDLE target
       property for details.

       If EXCLUDE_FROM_ALL is given the corresponding property will be set on
       the created target.  See documentation of the EXCLUDE_FROM_ALL target
       property for details.

       The add_executable command can also create IMPORTED executable targets
       using this signature:

         add_executable(<name> IMPORTED)

       An IMPORTED executable target references an executable file located
       outside the project.  No rules are generated to build it.  The target
       name has scope in the directory in which it is created and below.  It
       may be referenced like any target built within the project.  IMPORTED
       executables are useful for convenient reference from commands like
       add_custom_command.  Details about the imported executable are
       specified by setting properties whose names begin in "IMPORTED_".  The
       most important such property is IMPORTED_LOCATION (and its
       per-configuration version IMPORTED_LOCATION_<CONFIG>) which specifies
       the location of the main executable file on disk.  See documentation
       of the IMPORTED_* properties for more information.

  add_library
       Add a library to the project using the specified source files.

         add_library(<name> [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL]
                     source1 source2 ... sourceN)

       Adds a library target called <name> to be built from the source files
       listed in the command invocation.  The <name> corresponds to the
       logical target name and must be globally unique within a project.  The
       actual file name of the library built is constructed based on
       conventions of the native platform (such as lib<name>.a or
       <name>.lib).

       STATIC, SHARED, or MODULE may be given to specify the type of library
       to be created.  STATIC libraries are archives of object files for use
       when linking other targets.  SHARED libraries are linked dynamically
       and loaded at runtime.  MODULE libraries are plugins that are not
       linked into other targets but may be loaded dynamically at runtime
       using dlopen-like functionality.  If no type is given explicitly the
       type is STATIC or SHARED based on whether the current value of the
       variable BUILD_SHARED_LIBS is true.

       By default the library file will be created in the build tree
       directory corresponding to the source tree directory in which the
       command was invoked.  See documentation of the
       ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
       RUNTIME_OUTPUT_DIRECTORY target properties to change this location.
       See documentation of the OUTPUT_NAME target property to change the
       <name> part of the final file name.

       If EXCLUDE_FROM_ALL is given the corresponding property will be set on
       the created target.  See documentation of the EXCLUDE_FROM_ALL target
       property for details.

       The add_library command can also create IMPORTED library targets using
       this signature:

         add_library(<name> <SHARED|STATIC|MODULE|UNKNOWN> IMPORTED)

       An IMPORTED library target references a library file located outside
       the project.  No rules are generated to build it.  The target name has
       scope in the directory in which it is created and below.  It may be
       referenced like any target built within the project.  IMPORTED
       libraries are useful for convenient reference from commands like
       target_link_libraries.  Details about the imported library are
       specified by setting properties whose names begin in "IMPORTED_".  The
       most important such property is IMPORTED_LOCATION (and its
       per-configuration version IMPORTED_LOCATION_<CONFIG>) which specifies
       the location of the main library file on disk.  See documentation of
       the IMPORTED_* properties for more information.

  add_subdirectory
       Add a subdirectory to the build.

         add_subdirectory(source_dir [binary_dir] 
                          [EXCLUDE_FROM_ALL])

       Add a subdirectory to the build.  The source_dir specifies the
       directory in which the source CmakeLists.txt and code files are
       located.  If it is a relative path it will be evaluated with respect
       to the current directory (the typical usage), but it may also be an
       absolute path.  The binary_dir specifies the directory in which to
       place the output files.  If it is a relative path it will be evaluated
       with respect to the current output directory, but it may also be an
       absolute path.  If binary_dir is not specified, the value of
       source_dir, before expanding any relative path, will be used (the
       typical usage).  The CMakeLists.txt file in the specified source
       directory will be processed immediately by CMake before processing in
       the current input file continues beyond this command.

       If the EXCLUDE_FROM_ALL argument is provided then targets in the
       subdirectory will not be included in the ALL target of the parent
       directory by default, and will be excluded from IDE project files.
       Users must explicitly build targets in the subdirectory.  This is
       meant for use when the subdirectory contains a separate part of the
       project that is useful but not necessary, such as a set of examples.
       Typically the subdirectory should contain its own project() command
       invocation so that a full build system will be generated in the
       subdirectory (such as a VS IDE solution file).  Note that inter-target
       dependencies supercede this exclusion.  If a target built by the
       parent project depends on a target in the subdirectory, the dependee
       target will be included in the parent project build system to satisfy
       the dependency.

  add_test
       Add a test to the project with the specified arguments.

         add_test(testname Exename arg1 arg2 ...)

       If the ENABLE_TESTING command has been run, this command adds a test
       target to the current directory.  If ENABLE_TESTING has not been run,
       this command does nothing.  The tests are run by the testing subsystem
       by executing Exename with the specified arguments.  Exename can be
       either an executable built by this project or an arbitrary executable
       on the system (like tclsh).  The test will be run with the current
       working directory set to the CMakeList.txt files corresponding
       directory in the binary tree.

  aux_source_directory
       Find all source files in a directory.

         aux_source_directory(<dir> <variable>)

       Collects the names of all the source files in the specified directory
       and stores the list in the <variable> provided.  This command is
       intended to be used by projects that use explicit template
       instantiation.  Template instantiation files can be stored in a
       "Templates" subdirectory and collected automatically using this
       command to avoid manually listing all instantiations.

       It is tempting to use this command to avoid writing the list of source
       files for a library or executable target.  While this seems to work,
       there is no way for CMake to generate a build system that knows when a
       new source file has been added.  Normally the generated build system
       knows when it needs to rerun CMake because the CMakeLists.txt file is
       modified to add a new source.  When the source is just added to the
       directory without modifying this file, one would have to manually
       rerun CMake to generate a build system incorporating the new file.

  break
       Break from an enclosing foreach or while loop.

         break()

  build_command
       Get the command line that will build this project.

         build_command(<variable> <makecommand>)

       Sets the given <variable> to a string containing the command that will
       build this project from the root of the build tree using the build
       tool given by <makecommand>.  <makecommand> should be msdev, nmake,
       make or one of the end user build tools.  This is useful for
       configuring testing systems.

  cmake_minimum_required
       Set the minimum required version of cmake for a project.

         cmake_minimum_required(VERSION major[.minor[.patch]]
                                [FATAL_ERROR])

       If the current version of CMake is lower than that required it will
       stop processing the project and report an error.  When a version
       higher than 2.4 is specified the command implicitly invokes

         cmake_policy(VERSION major[.minor[.patch]])

       which sets the cmake policy version level to the version specified.
       When version 2.4 or lower is given the command implicitly invokes

         cmake_policy(VERSION 2.4)

       which enables compatibility features for CMake 2.4 and lower.

       The FATAL_ERROR option is accepted but ignored.  It is left from CMake
       versions 2.4 and lower in which failure to meet the minimum version
       was a warning by default.

  cmake_policy
       Manage CMake Policy settings.

       As CMake evolves it is sometimes necessary to change existing behavior
       in order to fix bugs or improve implementations of existing features.
       The CMake Policy mechanism is designed to help keep existing projects
       building as new versions of CMake introduce changes in behavior.  Each
       new policy (behavioral change) is given an identifier of the form
       "CMP<NNNN>" where "<NNNN>" is an integer index.  Documentation
       associated with each policy describes the OLD and NEW behavior and the
       reason the policy was introduced.  Projects may set each policy to
       select the desired behavior.  When CMake needs to know which behavior
       to use it checks for a setting specified by the project.  If no
       setting is available the OLD behavior is assumed and a warning is
       produced requesting that the policy be set.

       The cmake_policy command is used to set policies to OLD or NEW
       behavior.  While setting policies individually is supported, we
       encourage projects to set policies based on CMake versions.

         cmake_policy(VERSION major.minor[.patch])

       Specify that the current CMake list file is written for the given
       version of CMake.  All policies introduced in the specified version or
       earlier will be set to use NEW behavior.  All policies introduced
       after the specified version will be reset to use OLD behavior with a
       warning.  This effectively requests behavior preferred as of a given
       CMake version and tells newer CMake versions to warn about their new
       policies.  The policy version specified must be at least 2.4 or the
       command will report an error.  In order to get compatibility features
       supporting versions earlier than 2.4 see documentation of policy
       CMP0001.

         cmake_policy(SET CMP<NNNN> NEW)
         cmake_policy(SET CMP<NNNN> OLD)

       Tell CMake to use the OLD or NEW behavior for a given policy.
       Projects depending on the old behavior of a given policy may silence a
       policy warning by setting the policy state to OLD.  Alternatively one
       may fix the project to work with the new behavior and set the policy
       state to NEW.

         cmake_policy(GET CMP<NNNN> <variable>)

       Check whether a given policy is set to OLD or NEW behavior.  The
       output variable value will be "OLD" or "NEW" if the policy is set, and
       empty otherwise.

         cmake_policy(PUSH)
         cmake_policy(POP)

       Push and pop the current policy setting state on a stack.  Each PUSH
       must have a matching POP.  This is useful when mixing multiple
       projects, subprojects, and files included from external projects that
       may each have been written for a different version of CMake.  Each
       subdirectory entered by the project automatically pushes a new level
       on the stack to isolate the subdirectories from their parents.

  configure_file
       Copy a file to another location and modify its contents.

         configure_file(InputFile OutputFile
                        [COPYONLY] [ESCAPE_QUOTES] [@ONLY])

       The Input and Output files have to have full paths.  This command
       replaces any variables in the input file referenced as ${VAR} or @VAR@
       with their values as determined by CMake.  If a variable is not
       defined, it will be replaced with nothing.  If COPYONLY is specified,
       then no variable expansion will take place.  If ESCAPE_QUOTES is
       specified then any substituted quotes will be C-style escaped.  The
       file will be configured with the current values of CMake variables.
       If @ONLY is specified, only variables of the form @VAR@ will be
       replaces and ${VAR} will be ignored.  This is useful for configuring
       scripts that use ${VAR}.  Any occurrences of #cmakedefine VAR will be
       replaced with either #define VAR or /* #undef VAR */ depending on the
       setting of VAR in CMake

  create_test_sourcelist
       Create a test driver and source list for building test programs.

         create_test_sourcelist(sourceListName driverName
                                test1 test2 test3
                                EXTRA_INCLUDE include.h
                                FUNCTION function)

       A test driver is a program that links together many small tests into a
       single executable.  This is useful when building static executables
       with large libraries to shrink the total required size.  The list of
       source files needed to build the test driver will be in
       sourceListName.  DriverName is the name of the test driver program.
       The rest of the arguments consist of a list of test source files, can
       be semicolon separated.  Each test source file should have a function
       in it that is the same name as the file with no extension (foo.cxx
       should have int foo(int, char*[]);) DriverName will be able to call
       each of the tests by name on the command line.  If EXTRA_INCLUDE is
       specified, then the next argument is included into the generated file.
       If FUNCTION is specified, then the next argument is taken as a
       function name that is passed a pointer to ac and av.  This can be used
       to add extra command line processing to each test.  The cmake variable
       CMAKE_TESTDRIVER_BEFORE_TESTMAIN can be set to have code that will be
       placed directly before calling the test main function.
       CMAKE_TESTDRIVER_AFTER_TESTMAIN can be set to have code that will be
       placed directly after the call to the test main function.

  define_property
       Define and document custom properties.

         define_property(<GLOBAL | DIRECTORY | TARGET | SOURCE |
                          TEST | VARIABLE | CACHED_VARIABLE>
                          PROPERTY <name> [INHERITED]
                          BRIEF_DOCS <brief-doc>
                          FULL_DOCS <full-doc>)

       Define one property in a scope for use with the set_property and
       get_property commands.  This is primarily useful to associate
       documentation with property names that may be retrieved with the
       get_property command.  The first argument determines the kind of scope
       in which the property should be used.  It must be one of the
       following:

         GLOBAL    = associated with the global namespace
         DIRECTORY = associated with one directory
         TARGET    = associated with one target
         SOURCE    = associated with one source file
         TEST      = associated with a test named with add_test command
         VARIABLE  = documents a CMake language variable
         CACHED_VARIABLE = documents a CMake cache variable

       Note that unlike set_property and get_property no actual scope needs
       to be given; only the kind of scope is important.

       The required PROPERTY option is immediately followed by the name of
       the property being defined.

       If the INHERITED option then the get_property command will chain up to
       the next higher scope when the requested property is not set in the
       scope given to the command.  DIRECTORY scope chains to GLOBAL.
       TARGET, SOURCE, and TEST chain to DIRECTORY.

       The BRIEF_DOCS and FULL_DOCS options are followed by strings to be
       associated with the property as its brief and full documentation.
       Corresponding options to the get_property command will retrieve the
       documentation.

  enable_language
       Enable a language (CXX/C/Fortran/etc)

         enable_language(languageName [OPTIONAL] )

       This command enables support for the named language in CMake.  This is
       the same as the project command but does not create any of the extra
       variables that are created by the project command.  Example languages
       are CXX, C, Fortran.

       If OPTIONAL is used, use the CMAKE_<languageName>_COMPILER_WORKS
       variable to check whether the language has been enabled successfully.

  enable_testing
       Enable testing for current directory and below.

         enable_testing()

       Enables testing for this directory and below.  See also the add_test
       command.  Note that ctest expects to find a test file in the build
       directory root.  Therefore, this command should be in the source
       directory root.

  execute_process
       Execute one or more child processes.

         execute_process(COMMAND <cmd1> [args1...]]
                         [COMMAND <cmd2> [args2...] [...]]
                         [WORKING_DIRECTORY <directory>]
                         [TIMEOUT <seconds>]
                         [RESULT_VARIABLE <variable>]
                         [OUTPUT_VARIABLE <variable>]
                         [ERROR_VARIABLE <variable>]
                         [INPUT_FILE <file>]
                         [OUTPUT_FILE <file>]
                         [ERROR_FILE <file>]
                         [OUTPUT_QUIET]
                         [ERROR_QUIET]
                         [OUTPUT_STRIP_TRAILING_WHITESPACE]
                         [ERROR_STRIP_TRAILING_WHITESPACE])

       Runs the given sequence of one or more commands with the standard
       output of each process piped to the standard input of the next.  A
       single standard error pipe is used for all processes.  If
       WORKING_DIRECTORY is given the named directory will be set as the
       current working directory of the child processes.  If TIMEOUT is given
       the child processes will be terminated if they do not finish in the
       specified number of seconds (fractions are allowed).  If
       RESULT_VARIABLE is given the variable will be set to contain the
       result of running the processes.  This will be an integer return code
       from the last child or a string describing an error condition.  If
       OUTPUT_VARIABLE or ERROR_VARIABLE are given the variable named will be
       set with the contents of the standard output and standard error pipes
       respectively.  If the same variable is named for both pipes their
       output will be merged in the order produced.  If INPUT_FILE,
       OUTPUT_FILE, or ERROR_FILE is given the file named will be attached to
       the standard input of the first process, standard output of the last
       process, or standard error of all processes respectively.  If
       OUTPUT_QUIET or ERROR_QUIET is given then the standard output or
       standard error results will be quietly ignored.  If more than one
       OUTPUT_* or ERROR_* option is given for the same pipe the precedence
       is not specified.  If no OUTPUT_* or ERROR_* options are given the
       output will be shared with the corresponding pipes of the CMake
       process itself.

       The execute_process command is a newer more powerful version of
       exec_program, but the old command has been kept for compatibility.

  export
       Export targets from the build tree for use by outside projects.

         export(TARGETS [target1 [target2 [...]]] [NAMESPACE <namespace>]
                [APPEND] FILE <filename>)

       Create a file <filename> that may be included by outside projects to
       import targets from the current project's build tree.  This is useful
       during cross-compiling to build utility executables that can run on
       the host platform in one project and then import them into another
       project being compiled for the target platform.  If the NAMESPACE
       option is given the <namespace> string will be prepended to all target
       names written to the file.  If the APPEND option is given the
       generated code will be appended to the file instead of overwriting it.
       If a library target is included in the export but a target to which it
       links is not included the behavior is unspecified.

       The file created by this command is specific to the build tree and
       should never be installed.  See the install(EXPORT) command to export
       targets from an installation tree.

  file
       File manipulation command.

         file(WRITE filename "message to write"... )
         file(APPEND filename "message to write"... )
         file(READ filename variable [LIMIT numBytes] [OFFSET offset] [HEX])
         file(STRINGS filename variable [LIMIT_COUNT num]
              [LIMIT_INPUT numBytes] [LIMIT_OUTPUT numBytes]
              [LENGTH_MINIMUM numBytes] [LENGTH_MAXIMUM numBytes]
              [NEWLINE_CONSUME] [REGEX regex]
              [NO_HEX_CONVERSION])
         file(GLOB variable [RELATIVE path] [globbing expressions]...)
         file(GLOB_RECURSE variable [RELATIVE path] 
              [FOLLOW_SYMLINKS] [globbing expressions]...)
         file(REMOVE [file1 ...])
         file(REMOVE_RECURSE [file1 ...])
         file(MAKE_DIRECTORY [directory1 directory2 ...])
         file(RELATIVE_PATH variable directory file)
         file(TO_CMAKE_PATH path result)
         file(TO_NATIVE_PATH path result)
         file(DOWNLOAD url file [TIMEOUT timeout] [STATUS status] [LOG log])

       WRITE will write a message into a file called 'filename'.  It
       overwrites the file if it already exists, and creates the file if it
       does not exist.

       APPEND will write a message into a file same as WRITE, except it will
       append it to the end of the file

       READ will read the content of a file and store it into the variable.
       It will start at the given offset and read up to numBytes.  If the
       argument HEX is given, the binary data will be converted to
       hexadecimal representation and this will be stored in the variable.

       STRINGS will parse a list of ASCII strings from a file and store it in
       a variable.  Binary data in the file are ignored.  Carriage return
       (CR) characters are ignored.  It works also for Intel Hex and Motorola
       S-record files, which are automatically converted to binary format
       when reading them.  Disable this using NO_HEX_CONVERSION.

       LIMIT_COUNT sets the maximum number of strings to return.  LIMIT_INPUT
       sets the maximum number of bytes to read from the input file.
       LIMIT_OUTPUT sets the maximum number of bytes to store in the output
       variable.  LENGTH_MINIMUM sets the minimum length of a string to
       return.  Shorter strings are ignored.  LENGTH_MAXIMUM sets the maximum
       length of a string to return.  Longer strings are split into strings
       no longer than the maximum length.  NEWLINE_CONSUME allows newlines to
       be included in strings instead of terminating them.

       REGEX specifies a regular expression that a string must match to be
       returned.  Typical usage

         file(STRINGS myfile.txt myfile)

       stores a list in the variable "myfile" in which each item is a line
       from the input file.

       GLOB will generate a list of all files that match the globbing
       expressions and store it into the variable.  Globbing expressions are
       similar to regular expressions, but much simpler.  If RELATIVE flag is
       specified for an expression, the results will be returned as a
       relative path to the given path.

       Examples of globbing expressions include:

          *.cxx      - match all files with extension cxx
          *.vt?      - match all files with extension vta,...,vtz
          f[3-5].txt - match files f3.txt, f4.txt, f5.txt

       GLOB_RECURSE will generate a list similar to the regular GLOB, except
       it will traverse all the subdirectories of the matched directory and
       match the files.  Subdirectories that are symlinks are only traversed
       if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW.
       See cmake --help-policy CMP0009 for more information.

       Examples of recursive globbing include:

          /dir/*.py  - match all python files in /dir and subdirectories

       MAKE_DIRECTORY will create the given directories, also if their parent
       directories don't exist yet

       REMOVE will remove the given files, also in subdirectories

       REMOVE_RECURSE will remove the given files and directories, also
       non-empty directories

       RELATIVE_PATH will determine relative path from directory to the given
       file.

       TO_CMAKE_PATH will convert path into a cmake style path with unix /.
       The input can be a single path or a system path like "$ENV{PATH}".
       Note the double quotes around the ENV call TO_CMAKE_PATH only takes
       one argument.

       TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from a
       cmake style path into the native path style \ for windows and / for
       UNIX.

       DOWNLOAD will download the givin URL to the given file.  If LOG var is
       specified a log of the download will be put in var.  If STATUS var is
       specified the status of the operation will be put in var.  The status
       is returned in a list of length 2.  The first element is the numeric
       return value for the operation, and the second element is a string
       value for the error.  A 0 numeric error means no error in the
       operation.  If TIMEOUT time is specified, the operation will timeout
       after time seconds, time can be specified as a float.


  find_file
       Find the full path to a file.

          find_path(<VAR> name1 [path1 path2 ...])

       This is the short-hand signature for the command that is sufficient in
       many cases.  It is the same as find_path(<VAR> name1 [PATHS path1
       path2 ...])

          find_path(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                     ONLY_CMAKE_FIND_ROOT_PATH |
                     NO_CMAKE_FIND_ROOT_PATH]
                   )

       This command is used to find a full path to named file.  A cache entry
       named by <VAR> is created to store the result of this command.  If the
       full path to a file is found the result is stored in the variable and
       the search will not be repeated unless the variable is cleared.  If
       nothing is found, the result will be <VAR>-NOTFOUND, and the search
       will be attempted again the next time find_path is invoked with the
       same variable.  The name of the full path to a file that is searched
       for is specified by the names listed after the NAMES argument.
       Additional search locations can be specified after the PATHS argument.
       If ENV var is found in the HINTS or PATHS section the environment
       variable var will be read and converted from a system environment
       variable to a cmake style list of paths.  For example ENV PATH would
       be a way to list the system path variable.  The argument after DOC
       will be used for the documentation string in the cache.  PATH_SUFFIXES
       can be used to give sub directories that will be appended to the
       search paths.

       If NO_DEFAULT_PATH is specified, then no additional paths are added to
       the search.  If NO_DEFAULT_PATH is not specified, the search process
       is as follows:

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH

       3.  Search the paths specified by the HINTS option.  These should be
       paths computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

          PATH
          INCLUDE

       5.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH

       6.  Search the paths specified by the PATHS option or in the
       short-hand version of the command.  These are typically hard-coded
       guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_path(<VAR> NAMES name)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

  find_library
       Find a library.

          find_library(<VAR> name1 [path1 path2 ...])

       This is the short-hand signature for the command that is sufficient in
       many cases.  It is the same as find_library(<VAR> name1 [PATHS path1
       path2 ...])

          find_library(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                     ONLY_CMAKE_FIND_ROOT_PATH |
                     NO_CMAKE_FIND_ROOT_PATH]
                   )

       This command is used to find a library.  A cache entry named by <VAR>
       is created to store the result of this command.  If the library is
       found the result is stored in the variable and the search will not be
       repeated unless the variable is cleared.  If nothing is found, the
       result will be <VAR>-NOTFOUND, and the search will be attempted again
       the next time find_library is invoked with the same variable.  The
       name of the library that is searched for is specified by the names
       listed after the NAMES argument.  Additional search locations can be
       specified after the PATHS argument.  If ENV var is found in the HINTS
       or PATHS section the environment variable var will be read and
       converted from a system environment variable to a cmake style list of
       paths.  For example ENV PATH would be a way to list the system path
       variable.  The argument after DOC will be used for the documentation
       string in the cache.  PATH_SUFFIXES can be used to give sub
       directories that will be appended to the search paths.

       If NO_DEFAULT_PATH is specified, then no additional paths are added to
       the search.  If NO_DEFAULT_PATH is not specified, the search process
       is as follows:

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_LIBRARY_PATH
          CMAKE_FRAMEWORK_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_LIBRARY_PATH
          CMAKE_FRAMEWORK_PATH

       3.  Search the paths specified by the HINTS option.  These should be
       paths computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

          PATH
          LIB

       5.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          <prefix>/lib for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_LIBRARY_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH

       6.  Search the paths specified by the PATHS option or in the
       short-hand version of the command.  These are typically hard-coded
       guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_LIBRARY.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_library(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_library(<VAR> NAMES name)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

       If the library found is a framework, then VAR will be set to the full
       path to the framework <fullPath>/A.framework.  When a full path to a
       framework is used as a library, CMake will use a -framework A, and a
       -F<fullPath> to link the framework to the target.

  find_package
       Load settings for an external project.

         find_package(<package> [version] [EXACT] [QUIET]
                      [[REQUIRED|COMPONENTS] [components...]])

       Finds and loads settings from an external project.  <package>_FOUND
       will be set to indicate whether the package was found.  When the
       package is found package-specific information is provided through
       variables documented by the package itself.  The QUIET option disables
       messages if the package cannot be found.  The REQUIRED option stops
       processing with an error message if the package cannot be found.  A
       package-specific list of components may be listed after the REQUIRED
       option or after the COMPONENTS option if no REQUIRED option is given.
       The [version] argument requests a version with which the package found
       should be compatible (format is major[.minor[.patch[.tweak]]]).  The
       EXACT option requests that the version be matched exactly.  Version
       support is currently provided only on a package-by-package basis
       (details below).

       User code should generally look for packages using the above simple
       signature.  The remainder of this command documentation specifies the
       full command signature and details of the search process.  Project
       maintainers wishing to provide a package to be found by this command
       are encouraged to read on.

       The command has two modes by which it searches for packages: "Module"
       mode and "Config" mode.  Module mode is available when the command is
       invoked with the above reduced signature.  CMake searches for a file
       called "Find<package>.cmake" in the CMAKE_MODULE_PATH followed by the
       CMake installation.  If the file is found, it is read and processed by
       CMake.  It is responsible for finding the package, checking the
       version, and producing any needed messages.  Many find-modules provide
       limited or no support for versioning; check the module documentation.
       If no module is found the command proceeds to Config mode.

       The complete Config mode command signature is:

         find_package(<package> [version] [EXACT] [QUIET]
                      [[REQUIRED|COMPONENTS] [components...]] [NO_MODULE]
                      [NAMES name1 [name2 ...]]
                      [CONFIGS config1 [config2 ...]]
                      [HINTS path1 [path2 ... ]]
                      [PATHS path1 [path2 ... ]]
                      [PATH_SUFFIXES suffix1 [suffix2 ...]]
                      [NO_DEFAULT_PATH]
                      [NO_CMAKE_ENVIRONMENT_PATH]
                      [NO_CMAKE_PATH]
                      [NO_SYSTEM_ENVIRONMENT_PATH]
                      [NO_CMAKE_BUILDS_PATH]
                      [NO_CMAKE_SYSTEM_PATH]
                      [CMAKE_FIND_ROOT_PATH_BOTH |
                       ONLY_CMAKE_FIND_ROOT_PATH |
                       NO_CMAKE_FIND_ROOT_PATH])

       The NO_MODULE option may be used to skip Module mode explicitly.  It
       is also implied by use of options not specified in the reduced
       signature.

       Config mode attempts to locate a configuration file provided by the
       package to be found.  A cache entry called <package>_DIR is created to
       hold the directory containing the file.  By default the command
       searches for a package with the name <package>.  If the NAMES option
       is given the names following it are used instead of <package>.  The
       command searches for a file called "<name>Config.cmake" or
       "<lower-case-name>-config.cmake" for each name specified.  A
       replacement set of possible configuration file names may be given
       using the CONFIGS option.  The search procedure is specified below.
       Once found, the configuration file is read and processed by CMake.
       Since the file is provided by the package it already knows the
       location of package contents.  The full path to the configuration file
       is stored in the cmake variable <package>_CONFIG.

       If the package configuration file cannot be found CMake will generate
       an error describing the problem unless the QUIET argument is
       specified.  If REQUIRED is specified and the package is not found a
       fatal error is generated and the configure step stops executing.  If
       <package>_DIR has been set to a directory not containing a
       configuration file a fatal error is always generated because user
       intervention is required.

       When the [version] argument is given Config mode will only find a
       version of the package that claims compatibility with the requested
       version (format is major[.minor[.patch[.tweak]]]).  If the EXACT
       option is given only a version of the package claiming an exact match
       of the requested version may be found.  CMake does not establish any
       convention for the meaning of version numbers.  Package version
       numbers are checked by "version" files provided by the packages
       themselves.  For a candidate package confguration file
       "<config-file>.cmake" the corresponding version file is located next
       to it and named either "<config-file>-version.cmake" or
       "<config-file>Version.cmake".  If no such version file is available
       then the configuration file is assumed to not be compatible with any
       requested version.  When a version file is found it is loaded to check
       the requested version number.  The version file is loaded in a nested
       scope in which the following variables have been defined:

         PACKAGE_FIND_NAME          = the <package> name
         PACKAGE_FIND_VERSION       = full requested version string
         PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
         PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
         PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
         PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
         PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4

       The version file checks whether it satisfies the requested version and
       sets these variables:

         PACKAGE_VERSION            = full provided version string
         PACKAGE_VERSION_EXACT      = true if version is exact match
         PACKAGE_VERSION_COMPATIBLE = true if version is compatible

       These variables are checked by the find_package command to determine
       whether the configuration file provides an acceptable version.  They
       are not available after the find_package call returns.  If the version
       is acceptable the following variables are set:

         <package>_VERSION       = full provided version string
         <package>_VERSION_MAJOR = major version if provided, else 0
         <package>_VERSION_MINOR = minor version if provided, else 0
         <package>_VERSION_PATCH = patch version if provided, else 0
         <package>_VERSION_TWEAK = tweak version if provided, else 0
         <package>_VERSION_COUNT = number of version components, 0 to 4

       and the corresponding package configuration file is loaded.  When
       multiple package configuration files are available whose version files
       claim compatibility with the version requested it is unspecified which
       one is chosen.  No attempt is made to choose a highest or closest
       version number.

       Config mode provides an elaborate interface and search procedure.
       Much of the interface is provided for completeness and for use
       internally by find-modules loaded by Module mode.  Most user code
       should simply call

         find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])

       in order to find a package.  Package maintainers providing CMake
       package configuration files are encouraged to name and install them
       such that the procedure outlined below will find them without
       requiring use of additional options.

       CMake constructs a set of possible installation prefixes for the
       package.  Under each prefix several directories are searched for a
       configuration file.  The tables below show the directories searched.
       Each entry is meant for installation trees following Windows (W), UNIX
       (U), or Apple (A) conventions.

         <prefix>/                                               (W)
         <prefix>/(cmake|CMake)/                                 (W)
         <prefix>/(share|lib)/<name>*/                           (U)
         <prefix>/(share|lib)/<name>*/(cmake|CMake)/             (U)

       On systems supporting OS X Frameworks and Application Bundles the
       following directories are searched for frameworks or bundles
       containing a configuration file:

         <prefix>/<name>.framework/Resources/                    (A)
         <prefix>/<name>.framework/Resources/CMake/              (A)
         <prefix>/<name>.framework/Versions/*/Resources/         (A)
         <prefix>/<name>.framework/Versions/*/Resources/CMake/   (A)
         <prefix>/<name>.app/Contents/Resources/                 (A)
         <prefix>/<name>.app/Contents/Resources/CMake/           (A)

       In all cases the <name> is treated as case-insensitive and corresponds
       to any of the names specified (<package> or names given by NAMES).  If
       PATH_SUFFIXES is specified the suffixes are appended to each (W) or
       (U) directory entry one-by-one.

       This set of directories is intended to work in cooperation with
       projects that provide configuration files in their installation trees.
       Directories above marked with (W) are intended for installations on
       Windows where the prefix may point at the top of an application's
       installation directory.  Those marked with (U) are intended for
       installations on UNIX platforms where the prefix is shared by multiple
       packages.  This is merely a convention, so all (W) and (U) directories
       are still searched on all platforms.  Directories marked with (A) are
       intended for installations on Apple platforms.  The cmake variables
       CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE determine the order of
       preference as specified below.

       The set of installation prefixes is constructed using the following
       steps.  If NO_DEFAULT_PATH is specified all NO_* options are enabled.

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          CMAKE_PREFIX_PATH
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          CMAKE_PREFIX_PATH
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH

       3.  Search paths specified by the HINTS option.  These should be paths
       computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed.  Path entries ending
       in "/bin" or "/sbin" are automatically converted to their parent
       directories.

          PATH

       5.  Search project build trees recently configured in a CMake GUI.
       This can be skipped if NO_CMAKE_BUILDS_PATH is passed.  It is intended
       for the case when a user is building multiple dependent projects one
       after another.

       6.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH

       7.  Search paths specified by the PATHS option.  These are typically
       hard-coded guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_PACKAGE.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_package(<package> PATHS paths... NO_DEFAULT_PATH)
          find_package(<package>)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

  find_path
       Find the directory containing a file.

          find_path(<VAR> name1 [path1 path2 ...])

       This is the short-hand signature for the command that is sufficient in
       many cases.  It is the same as find_path(<VAR> name1 [PATHS path1
       path2 ...])

          find_path(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                     ONLY_CMAKE_FIND_ROOT_PATH |
                     NO_CMAKE_FIND_ROOT_PATH]
                   )

       This command is used to find a directory containing the named file.  A
       cache entry named by <VAR> is created to store the result of this
       command.  If the file in a directory is found the result is stored in
       the variable and the search will not be repeated unless the variable
       is cleared.  If nothing is found, the result will be <VAR>-NOTFOUND,
       and the search will be attempted again the next time find_path is
       invoked with the same variable.  The name of the file in a directory
       that is searched for is specified by the names listed after the NAMES
       argument.  Additional search locations can be specified after the
       PATHS argument.  If ENV var is found in the HINTS or PATHS section the
       environment variable var will be read and converted from a system
       environment variable to a cmake style list of paths.  For example ENV
       PATH would be a way to list the system path variable.  The argument
       after DOC will be used for the documentation string in the cache.
       PATH_SUFFIXES can be used to give sub directories that will be
       appended to the search paths.

       If NO_DEFAULT_PATH is specified, then no additional paths are added to
       the search.  If NO_DEFAULT_PATH is not specified, the search process
       is as follows:

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH

       3.  Search the paths specified by the HINTS option.  These should be
       paths computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

          PATH
          INCLUDE

       5.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH

       6.  Search the paths specified by the PATHS option or in the
       short-hand version of the command.  These are typically hard-coded
       guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_path(<VAR> NAMES name)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

       When searching for frameworks, if the file is specified as A/b.h, then
       the framework search will look for A.framework/Headers/b.h.  If that
       is found the path will be set to the path to the framework.  CMake
       will convert this to the correct -F option to include the file.

  find_program
       Find an executable program.

          find_program(<VAR> name1 [path1 path2 ...])

       This is the short-hand signature for the command that is sufficient in
       many cases.  It is the same as find_program(<VAR> name1 [PATHS path1
       path2 ...])

          find_program(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                     ONLY_CMAKE_FIND_ROOT_PATH |
                     NO_CMAKE_FIND_ROOT_PATH]
                   )

       This command is used to find a program.  A cache entry named by <VAR>
       is created to store the result of this command.  If the program is
       found the result is stored in the variable and the search will not be
       repeated unless the variable is cleared.  If nothing is found, the
       result will be <VAR>-NOTFOUND, and the search will be attempted again
       the next time find_program is invoked with the same variable.  The
       name of the program that is searched for is specified by the names
       listed after the NAMES argument.  Additional search locations can be
       specified after the PATHS argument.  If ENV var is found in the HINTS
       or PATHS section the environment variable var will be read and
       converted from a system environment variable to a cmake style list of
       paths.  For example ENV PATH would be a way to list the system path
       variable.  The argument after DOC will be used for the documentation
       string in the cache.  PATH_SUFFIXES can be used to give sub
       directories that will be appended to the search paths.

       If NO_DEFAULT_PATH is specified, then no additional paths are added to
       the search.  If NO_DEFAULT_PATH is not specified, the search process
       is as follows:

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_PROGRAM_PATH
          CMAKE_APPBUNDLE_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_PROGRAM_PATH
          CMAKE_APPBUNDLE_PATH

       3.  Search the paths specified by the HINTS option.  These should be
       paths computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

          PATH
          

       5.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          <prefix>/[s]bin for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_PROGRAM_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH

       6.  Search the paths specified by the PATHS option or in the
       short-hand version of the command.  These are typically hard-coded
       guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_PROGRAM.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_program(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_program(<VAR> NAMES name)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

  fltk_wrap_ui
       Create FLTK user interfaces Wrappers.

         fltk_wrap_ui(resultingLibraryName source1
                      source2 ... sourceN )

       Produce .h and .cxx files for all the .fl and .fld files listed.  The
       resulting .h and .cxx files will be added to a variable named
       resultingLibraryName_FLTK_UI_SRCS which should be added to your
       library.

  foreach
       Evaluate a group of commands for each value in a list.

         foreach(loop_var arg1 arg2 ...)
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endforeach(loop_var)
         foreach(loop_var RANGE total)
         foreach(loop_var RANGE start stop [step])

       All commands between foreach and the matching endforeach are recorded
       without being invoked.  Once the endforeach is evaluated, the recorded
       list of commands is invoked once for each argument listed in the
       original foreach command.  Before each iteration of the loop
       "${loop_var}" will be set as a variable with the current value in the
       list.

       Foreach can also iterate over a generated range of numbers.  There are
       three types of this iteration:

       * When specifying single number, the range will have elements 0 to
       "total".

       * When specifying two numbers, the range will have elements from the
       first number to the second number.

       * The third optional number is the increment used to iterate from the
       first number to the second number.

  function
       Start recording a function for later invocation as a command.

         function(<name> [arg1 [arg2 [arg3 ...]]])
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endfunction(<name>)

       Define a function named <name> that takes arguments named arg1 arg2
       arg3 (...).  Commands listed after function, but before the matching
       endfunction, are not invoked until the function is invoked.  When it
       is invoked, the commands recorded in the function are first modified
       by replacing formal parameters (${arg1}) with the arguments passed,
       and then invoked as normal commands.  In addition to referencing the
       formal parameters you can reference the variable ARGC which will be
       set to the number of arguments passed into the function as well as
       ARGV0 ARGV1 ARGV2 ...  which will have the actual values of the
       arguments passed in.  This facilitates creating functions with
       optional arguments.  Additionally ARGV holds the list of all arguments
       given to the function and ARGN holds the list of argument pass the
       last expected argument.

  get_cmake_property
       Get a property of the CMake instance.

         get_cmake_property(VAR property)

       Get a property from the CMake instance.  The value of the property is
       stored in the variable VAR.  If the property is not found, CMake will
       report an error.  Some supported properties include: VARIABLES,
       CACHE_VARIABLES, COMMANDS, MACROS, and COMPONENTS.

  get_directory_property
       Get a property of the directory.

         get_directory_property(VAR [DIRECTORY dir] property)

       Get a property from the Directory.  The value of the property is
       stored in the variable VAR.  If the property is not found, CMake will
       report an error.  The properties include: VARIABLES, CACHE_VARIABLES,
       COMMANDS, MACROS, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, DEFINITIONS,
       INCLUDE_REGULAR_EXPRESSION, LISTFILE_STACK, PARENT_DIRECTORY, and
       DEFINITION varname.  If the DIRECTORY argument is provided then the
       property of the provided directory will be retrieved instead of the
       current directory.  You can only get properties of a directory during
       or after it has been traversed by cmake.

  get_filename_component
       Get a specific component of a full filename.

         get_filename_component(VarName FileName
                                PATH|ABSOLUTE|NAME|EXT|NAME_WE
                                [CACHE])

       Set VarName to be the path (PATH), file name (NAME), file extension
       (EXT), file name without extension (NAME_WE) of FileName, or the full
       absolute (ABSOLUTE) file name without symlinks.  Note that the path is
       converted to Unix slashes format and has no trailing slashes.  The
       longest file extension is always considered.  If the optional CACHE
       argument is specified, the result variable is added to the cache.

         get_filename_component(VarName FileName
                                PROGRAM [PROGRAM_ARGS ArgVar]
                                [CACHE])

       The program in FileName will be found in the system search path or
       left as a full path.  If PROGRAM_ARGS is present with PROGRAM, then
       any command-line arguments present in the FileName string are split
       from the program name and stored in ArgVar.  This is used to separate
       a program name from its arguments in a command line string.

  get_property
       Get a property.

         get_property(<variable>
                      <GLOBAL             |
                       DIRECTORY [dir]    |
                       TARGET    <target> |
                       SOURCE    <source> |
                       TEST      <test>   |
                       VARIABLE>
                      PROPERTY <name>
                      [SET | DEFINED | BRIEF_DOCS | FULL_DOCS])

       Get one property from one object in a scope.  The first argument
       specifies the variable in which to store the result.  The second
       argument determines the scope from which to get the property.  It must
       be one of the following:

       GLOBAL scope is unique and does not accept a name.

       DIRECTORY scope defaults to the current directory but another
       directory (already processed by CMake) may be named by full or
       relative path.

       TARGET scope must name one existing target.

       SOURCE scope must name one source file.

       TEST scope must name one existing test.

       VARIABLE scope is unique and does not accept a name.

       The required PROPERTY option is immediately followed by the name of
       the property to get.  If the property is not set an empty value is
       returned.  If the SET option is given the variable is set to a boolean
       value indicating whether the property has been set.  If the DEFINED
       option is given the variable is set to a boolean value indicating
       whether the property has been defined such as with define_property.
       If BRIEF_DOCS or FULL_DOCS is given then the variable is set to a
       string containing documentation for the requested property.  If
       documentation is requested for a property that has not been defined
       NOTFOUND is returned.

  get_source_file_property
       Get a property for a source file.

         get_source_file_property(VAR file property)

       Get a property from a source file.  The value of the property is
       stored in the variable VAR.  If the property is not found, VAR will be
       set to "NOTFOUND".  Use set_source_files_properties to set property
       values.  Source file properties usually control how the file is built.
       One property that is always there is LOCATION

  get_target_property
       Get a property from a target.

         get_target_property(VAR target property)

       Get a property from a target.  The value of the property is stored in
       the variable VAR.  If the property is not found, VAR will be set to
       "NOTFOUND".  Use set_target_properties to set property values.
       Properties are usually used to control how a target is built.

       The read-only property "<CONFIG>_LOCATION" provides the full path to
       the file on disk that will be created for the target when building
       under configuration <CONFIG> (in upper-case, such as
       "DEBUG_LOCATION").  The read-only property "LOCATION" specifies the
       full path to the file on disk that will be created for the target.
       The path may contain a build-system-specific portion that is replaced
       at build time with the configuration getting built (such as
       "$(ConfigurationName)" in VS).  This is very useful for executable
       targets to get the path to the executable file for use in a custom
       command.

       The read-only property "TYPE" returns which type the specified target
       has (EXECUTABLE, STATIC_LIBRARY, SHARED_LIBRARY, MODULE_LIBRARY,
       UTILITY, INSTALL_FILES or INSTALL_PROGRAMS).  This command can get
       properties for any target so far created.  The targets do not need to
       be in the current CMakeLists.txt file.

  get_test_property
       Get a property of the test.

         get_test_property(test VAR property)

       Get a property from the Test.  The value of the property is stored in
       the variable VAR.  If the property is not found, CMake will report an
       error.  For a list of standard properties you can type cmake
       --help-property-list

  if
       Conditionally execute a group of commands.

         if(expression)
           # then section.
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         elseif(expression2)
           # elseif section.
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         else(expression)
           # else section.
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endif(expression)

       Evaluates the given expression.  If the result is true, the commands
       in the THEN section are invoked.  Otherwise, the commands in the else
       section are invoked.  The elseif and else sections are optional.  You
       may have multiple elseif clauses.  Note that the same expression must
       be given to if, and endif.  Long expressions can be used and the order
       or precedence is that the EXISTS, COMMAND, and DEFINED operators will
       be evaluated first.  Then any EQUAL, LESS, GREATER, STRLESS,
       STRGREATER, STREQUAL, MATCHES will be evaluated.  Then NOT operators
       and finally AND, OR operators will be evaluated.  Possible expressions
       are:

         if(variable)

       True if the variable's value is not empty, 0, N, NO, OFF, FALSE,
       NOTFOUND, or <variable>-NOTFOUND.

         if(NOT variable)

       True if the variable's value is empty, 0, N, NO, OFF, FALSE, NOTFOUND,
       or <variable>-NOTFOUND.

         if(variable1 AND variable2)

       True if both variables would be considered true individually.

         if(variable1 OR variable2)

       True if either variable would be considered true individually.

         if(COMMAND command-name)

       True if the given name is a command, macro or function that can be
       invoked.

         if(POLICY policy-id)

       True if the given name is an existing policy (of the form CMP<NNNN>).

         if(TARGET target-name)

       True if the given name is an existing target, built or imported.

         if(EXISTS file-name)
         if(EXISTS directory-name)

       True if the named file or directory exists.  Behavior is well-defined
       only for full paths.

         if(file1 IS_NEWER_THAN file2)

       True if file1 is newer than file2 or if one of the two files doesn't
       exist.  Behavior is well-defined only for full paths.

         if(IS_DIRECTORY directory-name)

       True if the given name is a directory.  Behavior is well-defined only
       for full paths.

         if(IS_ABSOLUTE path)

       True if the given path is an absolute path.

          if(variable MATCHES regex)
         if(string MATCHES regex)

       True if the given string or variable's value matches the given regular
       expression.

         if(variable LESS number)
         if(string LESS number)
         if(variable GREATER number)
         if(string GREATER number)
         if(variable EQUAL number)
         if(string EQUAL number)

       True if the given string or variable's value is a valid number and the
       inequality or equality is true.

         if(variable STRLESS string)
         if(string STRLESS string)
         if(variable STRGREATER string)
         if(string STRGREATER string)
         if(variable STREQUAL string)
         if(string STREQUAL string)

       True if the given string or variable's value is lexicographically less
       (or greater, or equal) than the string on the right.

         if(version1 VERSION_LESS version2)
         if(version1 VERSION_EQUAL version2)
         if(version1 VERSION_GREATER version2)

       Component-wise integer version number comparison (version format is
       major[.minor[.patch[.tweak]]]).

         if(DEFINED variable)

       True if the given variable is defined.  It does not matter if the
       variable is true or false just if it has been set.

  include
       Read CMake listfile code from the given file.

         include(file1 [OPTIONAL] [RESULT_VARIABLE <VAR>])
         include(module [OPTIONAL] [RESULT_VARIABLE <VAR>])

       Reads CMake listfile code from the given file.  Commands in the file
       are processed immediately as if they were written in place of the
       include command.  If OPTIONAL is present, then no error is raised if
       the file does not exist.  If RESULT_VARIABLE is given the variable
       will be set to the full filename which has been included or NOTFOUND
       if it failed.

       If a module is specified instead of a file, the file with name
       <modulename>.cmake is searched in the CMAKE_MODULE_PATH.

  include_directories
       Add include directories to the build.

         include_directories([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)

       Add the given directories to those searched by the compiler for
       include files.  By default the directories are appended onto the
       current list of directories.  This default behavior can be changed by
       setting CMAKE_include_directories_BEFORE to ON.  By using BEFORE or
       AFTER you can select between appending and prepending, independent
       from the default.  If the SYSTEM option is given the compiler will be
       told that the directories are meant as system include directories on
       some platforms.

  include_external_msproject
       Include an external Microsoft project file in a workspace.

         include_external_msproject(projectname location
                                    dep1 dep2 ...)

       Includes an external Microsoft project in the generated workspace
       file.  Currently does nothing on UNIX.

  include_regular_expression
       Set the regular expression used for dependency checking.

         include_regular_expression(regex_match [regex_complain])

       Set the regular expressions used in dependency checking.  Only files
       matching regex_match will be traced as dependencies.  Only files
       matching regex_complain will generate warnings if they cannot be found
       (standard header paths are not searched).  The defaults are:

         regex_match    = "^.*$" (match everything)
         regex_complain = "^$" (match empty string only)

  install
       Specify rules to run at install time.

       This command generates installation rules for a project.  Rules
       specified by calls to this command within a source directory are
       executed in order during installation.  The order across directories
       is not defined.

       There are multiple signatures for this command.  Some of them define
       installation properties for files and targets.  Properties common to
       multiple signatures are covered here but they are valid only for
       signatures that specify them.

       DESTINATION arguments specify the directory on disk to which a file
       will be installed.  If a full path (with a leading slash or drive
       letter) is given it is used directly.  If a relative path is given it
       is interpreted relative to the value of CMAKE_INSTALL_PREFIX.

       PERMISSIONS arguments specify permissions for installed files.  Valid
       permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ,
       GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE,
       SETUID, and SETGID.  Permissions that do not make sense on certain
       platforms are ignored on those platforms.

       The CONFIGURATIONS argument specifies a list of build configurations
       for which the install rule applies (Debug, Release, etc.).

       The COMPONENT argument specifies an installation component name with
       which the install rule is associated, such as "runtime" or
       "development".  During component-specific installation only install
       rules associated with the given component name will be executed.
       During a full installation all components are installed.

       The RENAME argument specifies a name for an installed file that may be
       different from the original file.  Renaming is allowed only when a
       single file is installed by the command.

       The OPTIONAL argument specifies that it is not an error if the file to
       be installed does not exist.

       The TARGETS signature:

         install(TARGETS targets... [EXPORT <export-name>]
                 [[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
                   PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
                  [DESTINATION <dir>]
                  [PERMISSIONS permissions...]
                  [CONFIGURATIONS [Debug|Release|...]]
                  [COMPONENT <component>]
                  [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
                 ] [...])

       The TARGETS form specifies rules for installing targets from a
       project.  There are five kinds of target files that may be installed:
       ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE.  Executables are
       treated as RUNTIME targets, except that those marked with the
       MACOSX_BUNDLE property are treated as BUNDLE targets on OS X.  Static
       libraries are always treated as ARCHIVE targets.  Module libraries are
       always treated as LIBRARY targets.  For non-DLL platforms shared
       libraries are treated as LIBRARY targets, except that those marked
       with the FRAMEWORK property are treated as FRAMEWORK targets on OS X.
       For DLL platforms the DLL part of a shared library is treated as a
       RUNTIME target and the corresponding import library is treated as an
       ARCHIVE target.  All Windows-based systems including Cygwin are DLL
       platforms.  The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK arguments
       change the type of target to which the subsequent properties apply.
       If none is given the installation properties apply to all target
       types.  If only one is given then only targets of that type will be
       installed (which can be used to install just a DLL or just an import
       library).

       The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause
       subsequent properties to be applied to installing a FRAMEWORK shared
       library target's associated files on non-Apple platforms.  Rules
       defined by these arguments are ignored on Apple platforms because the
       associated files are installed into the appropriate locations inside
       the framework folder.  See documentation of the PRIVATE_HEADER,
       PUBLIC_HEADER, and RESOURCE target properties for details.

       Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY
       option.  On some platforms a versioned shared library has a symbolic
       link such as

         lib<name>.so -> lib<name>.so.1

       where "lib<name>.so.1" is the soname of the library and "lib<name>.so"
       is a "namelink" allowing linkers to find the library when given
       "-l<name>".  The NAMELINK_ONLY option causes installation of only the
       namelink when a library target is installed.  The NAMELINK_SKIP option
       causes installation of library files other than the namelink when a
       library target is installed.  When neither option is given both
       portions are installed.  On platforms where versioned shared libraries
       do not have namelinks or when a library is not versioned the
       NAMELINK_SKIP option installs the library and the NAMELINK_ONLY option
       installs nothing.  See the VERSION and SOVERSION target properties for
       details on creating versioned shared libraries.

       One or more groups of properties may be specified in a single call to
       the TARGETS form of this command.  A target may be installed more than
       once to different locations.  Consider hypothetical targets "myExe",
       "mySharedLib", and "myStaticLib".  The code

           install(TARGETS myExe mySharedLib myStaticLib
                   RUNTIME DESTINATION bin
                   LIBRARY DESTINATION lib
                   ARCHIVE DESTINATION lib/static)
           install(TARGETS mySharedLib DESTINATION /some/full/path)

       will install myExe to <prefix>/bin and myStaticLib to
       <prefix>/lib/static.  On non-DLL platforms mySharedLib will be
       installed to <prefix>/lib and /some/full/path.  On DLL platforms the
       mySharedLib DLL will be installed to <prefix>/bin and /some/full/path
       and its import library will be installed to <prefix>/lib/static and
       /some/full/path.  On non-DLL platforms mySharedLib will be installed
       to <prefix>/lib and /some/full/path.

       The EXPORT option associates the installed target files with an export
       called <export-name>.  It must appear before any RUNTIME, LIBRARY, or
       ARCHIVE options.  See documentation of the install(EXPORT ...)
       signature below for details.

       Installing a target with EXCLUDE_FROM_ALL set to true has undefined
       behavior.

       The FILES signature:

         install(FILES files... DESTINATION <dir>
                 [PERMISSIONS permissions...]
                 [CONFIGURATIONS [Debug|Release|...]]
                 [COMPONENT <component>]
                 [RENAME <name>] [OPTIONAL])

       The FILES form specifies rules for installing files for a project.
       File names given as relative paths are interpreted with respect to the
       current source directory.  Files installed by this form are by default
       given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ
       if no PERMISSIONS argument is given.

       The PROGRAMS signature:

         install(PROGRAMS files... DESTINATION <dir>
                 [PERMISSIONS permissions...]
                 [CONFIGURATIONS [Debug|Release|...]]
                 [COMPONENT <component>]
                 [RENAME <name>] [OPTIONAL])

       The PROGRAMS form is identical to the FILES form except that the
       default permissions for the installed file also include OWNER_EXECUTE,
       GROUP_EXECUTE, and WORLD_EXECUTE.  This form is intended to install
       programs that are not targets, such as shell scripts.  Use the TARGETS
       form to install targets built within the project.

       The DIRECTORY signature:

         install(DIRECTORY dirs... DESTINATION <dir>
                 [FILE_PERMISSIONS permissions...]
                 [DIRECTORY_PERMISSIONS permissions...]
                 [USE_SOURCE_PERMISSIONS]
                 [CONFIGURATIONS [Debug|Release|...]]
                 [COMPONENT <component>] [FILES_MATCHING]
                 [[PATTERN <pattern> | REGEX <regex>]
                  [EXCLUDE] [PERMISSIONS permissions...]] [...])

       The DIRECTORY form installs contents of one or more directories to a
       given destination.  The directory structure is copied verbatim to the
       destination.  The last component of each directory name is appended to
       the destination directory but a trailing slash may be used to avoid
       this because it leaves the last component empty.  Directory names
       given as relative paths are interpreted with respect to the current
       source directory.  If no input directory names are given the
       destination directory will be created but nothing will be installed
       into it.  The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options
       specify permissions given to files and directories in the destination.
       If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not,
       file permissions will be copied from the source directory structure.
       If no permissions are specified files will be given the default
       permissions specified in the FILES form of the command, and the
       directories will be given the default permissions specified in the
       PROGRAMS form of the command.

       Installation of directories may be controlled with fine granularity
       using the PATTERN or REGEX options.  These "match" options specify a
       globbing pattern or regular expression to match directories or files
       encountered within input directories.  They may be used to apply
       certain options (see below) to a subset of the files and directories
       encountered.  The full path to each input file or directory (with
       forward slashes) is matched against the expression.  A PATTERN will
       match only complete file names: the portion of the full path matching
       the pattern must occur at the end of the file name and be preceded by
       a slash.  A REGEX will match any portion of the full path but it may
       use '/' and '$' to simulate the PATTERN behavior.  By default all
       files and directories are installed whether or not they are matched.
       The FILES_MATCHING option may be given before the first match option
       to disable installation of files (but not directories) not matched by
       any expression.  For example, the code

         install(DIRECTORY src/ DESTINATION include/myproj
                 FILES_MATCHING PATTERN "*.h")

       will extract and install header files from a source tree.

       Some options may follow a PATTERN or REGEX expression and are applied
       only to files or directories matching them.  The EXCLUDE option will
       skip the matched file or directory.  The PERMISSIONS option overrides
       the permissions setting for the matched file or directory.  For
       example the code

         install(DIRECTORY icons scripts/ DESTINATION share/myproj
                 PATTERN "CVS" EXCLUDE
                 PATTERN "scripts/*"
                 PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ
                             GROUP_EXECUTE GROUP_READ)

       will install the icons directory to share/myproj/icons and the scripts
       directory to share/myproj.  The icons will get default file
       permissions, the scripts will be given specific permissions, and any
       CVS directories will be excluded.

       The SCRIPT and CODE signature:

         install([[SCRIPT <file>] [CODE <code>]] [...])

       The SCRIPT form will invoke the given CMake script files during
       installation.  If the script file name is a relative path it will be
       interpreted with respect to the current source directory.  The CODE
       form will invoke the given CMake code during installation.  Code is
       specified as a single argument inside a double-quoted string.  For
       example, the code

         install(CODE "MESSAGE(\"Sample install message.\")")

       will print a message during installation.

       The EXPORT signature:

         install(EXPORT <export-name> DESTINATION <dir>
                 [NAMESPACE <namespace>] [FILE <name>.cmake]
                 [PERMISSIONS permissions...]
                 [CONFIGURATIONS [Debug|Release|...]]
                 [COMPONENT <component>])

       The EXPORT form generates and installs a CMake file containing code to
       import targets from the installation tree into another project.
       Target installations are associated with the export <export-name>
       using the EXPORT option of the install(TARGETS ...) signature
       documented above.  The NAMESPACE option will prepend <namespace> to
       the target names as they are written to the import file.  By default
       the generated file will be called <export-name>.cmake but the FILE
       option may be used to specify a different name.  The value given to
       the FILE option must be a file name with the ".cmake" extension.  If a
       CONFIGURATIONS option is given then the file will only be installed
       when one of the named configurations is installed.  Additionally, the
       generated import file will reference only the matching target
       configurations.  If a COMPONENT option is specified that does not
       match that given to the targets associated with <export-name> the
       behavior is undefined.  If a library target is included in the export
       but a target to which it links is not included the behavior is
       unspecified.

       The EXPORT form is useful to help outside projects use targets built
       and installed by the current project.  For example, the code

         install(TARGETS myexe EXPORT myproj DESTINATION bin)
         install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)

       will install the executable myexe to <prefix>/bin and code to import
       it in the file "<prefix>/lib/myproj/myproj.cmake".  An outside project
       may load this file with the include command and reference the myexe
       executable from the installation tree using the imported target name
       mp_myexe as if the target were built in its own tree.

       NOTE: This command supercedes the INSTALL_TARGETS command and the
       target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT.  It also
       replaces the FILES forms of the INSTALL_FILES and INSTALL_PROGRAMS
       commands.  The processing order of these install rules relative to
       those generated by INSTALL_TARGETS, INSTALL_FILES, and
       INSTALL_PROGRAMS commands is not defined.


  link_directories
       Specify directories in which the linker will look for libraries.

         link_directories(directory1 directory2 ...)

       Specify the paths in which the linker should search for libraries.
       The command will apply only to targets created after it is called.

  list
       List operations.

         list(LENGTH <list> <output variable>)
         list(GET <list> <element index> [<element index> ...] <output variable>)
         list(APPEND <list> <element> [<element> ...])
         list(FIND <list> <value> <output variable>)
         list(INSERT <list> <element_index> <element> [<element> ...])
         list(REMOVE_ITEM <list> <value> [<value> ...])
         list(REMOVE_AT <list> <index> [<index> ...])
         list(REMOVE_DUPLICATES <list>)
         list(REVERSE <list>)
         list(SORT <list>)

       LENGTH will return a given list's length.

       GET will return list of elements specified by indices from the list.

       APPEND will append elements to the list.

       FIND will return the index of the element specified in the list or -1
       if it wasn't found.

       INSERT will insert elements to the list to the specified location.

       REMOVE_AT and REMOVE_ITEM will remove items from the list.  The
       difference is that REMOVE_ITEM will remove the given items, while
       REMOVE_AT will remove the items at the given indices.

       REMOVE_DUPLICATES will remove duplicated items in the list.

       REVERSE reverses the contents of the list in-place.

       SORT sorts the list in-place alphabetically.

       NOTES: A list in cmake is a ; separated group of strings.  To create a
       list the set command can be used.  For example, set(var a b c d e)
       creates a list with a;b;c;d;e, and set(var "a b c d e") creates a
       string or a list with one item in it.

       When specifying index values, if <element index> is 0 or greater, it
       is indexed from the beginning of the list, with 0 representing the
       first list element.  If <element index> is -1 or lesser, it is indexed
       from the end of the list, with -1 representing the last list element.
       Be careful when counting with negative indices: they do not start from
       0.  -0 is equivalent to 0, the first list element.


  load_cache
       Load in the values from another project's CMake cache.

         load_cache(pathToCacheFile READ_WITH_PREFIX
                    prefix entry1...)

       Read the cache and store the requested entries in variables with their
       name prefixed with the given prefix.  This only reads the values, and
       does not create entries in the local project's cache.

         load_cache(pathToCacheFile [EXCLUDE entry1...]
                    [INCLUDE_INTERNALS entry1...])

       Load in the values from another cache and store them in the local
       project's cache as internal entries.  This is useful for a project
       that depends on another project built in a different tree.  EXCLUDE
       option can be used to provide a list of entries to be excluded.
       INCLUDE_INTERNALS can be used to provide a list of internal entries to
       be included.  Normally, no internal entries are brought in.  Use of
       this form of the command is strongly discouraged, but it is provided
       for backward compatibility.

  load_command
       Load a command into a running CMake.

         load_command(COMMAND_NAME <loc1> [loc2 ...])

       The given locations are searched for a library whose name is
       cmCOMMAND_NAME.  If found, it is loaded as a module and the command is
       added to the set of available CMake commands.  Usually, TRY_COMPILE is
       used before this command to compile the module.  If the command is
       successfully loaded a variable named

         CMAKE_LOADED_COMMAND_<COMMAND_NAME>

       will be set to the full path of the module that was loaded.  Otherwise
       the variable will not be set.

  macro
       Start recording a macro for later invocation as a command.

         macro(<name> [arg1 [arg2 [arg3 ...]]])
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endmacro(<name>)

       Define a macro named <name> that takes arguments named arg1 arg2 arg3
       (...).  Commands listed after macro, but before the matching endmacro,
       are not invoked until the macro is invoked.  When it is invoked, the
       commands recorded in the macro are first modified by replacing formal
       parameters (${arg1}) with the arguments passed, and then invoked as
       normal commands.  In addition to referencing the formal parameters you
       can reference the values ${ARGC} which will be set to the number of
       arguments passed into the function as well as ${ARGV0} ${ARGV1}
       ${ARGV2} ...  which will have the actual values of the arguments
       passed in.  This facilitates creating macros with optional arguments.
       Additionally ${ARGV} holds the list of all arguments given to the
       macro and ${ARGN} holds the list of argument pass the last expected
       argument.  Note that the parameters to a macro and values such as ARGN
       are not variables in the usual CMake sense.  They are string
       replacements much like the c preprocessor would do with a macro.  If
       you want true CMake variables you should look at the function command.

  mark_as_advanced
       Mark cmake cached variables as advanced.

         mark_as_advanced([CLEAR|FORCE] VAR VAR2 VAR...)

       Mark the named cached variables as advanced.  An advanced variable
       will not be displayed in any of the cmake GUIs unless the show
       advanced option is on.  If CLEAR is the first argument advanced
       variables are changed back to unadvanced.  If FORCE is the first
       argument, then the variable is made advanced.  If neither FORCE nor
       CLEAR is specified, new values will be marked as advanced, but if the
       variable already has an advanced/non-advanced state, it will not be
       changed.

       It does nothing in script mode.

  math
       Mathematical expressions.

         math(EXPR <output variable> <math expression>)

       EXPR evaluates mathematical expression and return result in the output
       variable.  Example mathematical expression is '5 * ( 10 + 13 )'.
       Supported operators are + - * / % | & ^ ~ << >> * / %.  They have the
       same meaning as they do in c code.

  message
       Display a message to the user.

         message([SEND_ERROR | STATUS | FATAL_ERROR]
                 "message to display" ...)

       By default the message is displayed in a pop up window (CMakeSetup),
       or in the stdout of cmake, or the error section of ccmake.  If the
       first argument is SEND_ERROR then an error is raised, and the generate
       phase will be skipped.  If the first argument is FATAL_ERROR, all
       processing is halted.  If the first argument is STATUS then the
       message is displayed in the progress line for the GUI, or with a -- in
       the command line cmake.

  option
       Provides an option that the user can optionally select.

         option(<option_variable> "help string describing option"
                [initial value])

       Provide an option for the user to select as ON or OFF.  If no initial
       value is provided, OFF is used.

  output_required_files
       Output a list of required source files for a specified source file.

         output_required_files(srcfile outputfile)

       Outputs a list of all the source files that are required by the
       specified srcfile.  This list is written into outputfile.  This is
       similar to writing out the dependencies for srcfile except that it
       jumps from .h files into .cxx, .c and .cpp files if possible.

  project
       Set a name for the entire project.

         project(projectname [CXX] [C] [Java])

       Sets the name of the project.  This creates the variables
       projectname_BINARY_DIR and projectname_SOURCE_DIR.  Optionally you can
       specify which languages your project supports.  By default all
       languages are supported.  If you do not have a C++ compiler, but want
       to build a c program with cmake, then use this option.

  qt_wrap_cpp
       Create Qt Wrappers.

         qt_wrap_cpp(resultingLibraryName DestName
                     SourceLists ...)

       Produce moc files for all the .h files listed in the SourceLists.  The
       moc files will be added to the library using the DestName source list.

  qt_wrap_ui
       Create Qt user interfaces Wrappers.

         qt_wrap_ui(resultingLibraryName HeadersDestName
                    SourcesDestName SourceLists ...)

       Produce .h and .cxx files for all the .ui files listed in the
       SourceLists.  The .h files will be added to the library using the
       HeadersDestNamesource list.  The .cxx files will be added to the
       library using the SourcesDestNamesource list.

  remove_definitions
       Removes -D define flags added by add_definitions.

         remove_definitions(-DFOO -DBAR ...)

       Removes flags (added by add_definitions) from the compiler command
       line for sources in the current directory and below.

  return
       Return from a file, directory or function.

         return()

       Returns from a file, directory or function.  When this command is
       encountered in an included file (via include() or find_package()), it
       causes processing of the current file to stop and control is returned
       to the including file.  If it is encountered in a file which is not
       included by another file, e.g.  a CMakeLists.txt, control is returned
       to the parent directory if there is one.  If return is called in a
       function, control is returned to the caller of the function.  Note
       that a macro is not a function and does not handle return like a
       function does.

  separate_arguments
       Split space separated arguments into a semi-colon separated list.

         separate_arguments(VARIABLE)

       Convert the value of VARIABLE to a semi-colon separated list.  All
       spaces are replaced with ';'.  This helps with generating command
       lines.

  set
       Set a CMAKE variable to a given value.

         set(<variable> <value> [[CACHE <type> <docstring> [FORCE]] | PARENT_SCOPE])

       Within CMake sets <variable> to the value <value>.  <value> is
       expanded before <variable> is set to it.  If CACHE is present, then
       the <variable> is put in the cache.  <type> and <docstring> are then
       required.  <type> is used by the CMake GUI to choose a widget with
       which the user sets a value.  The value for <type> may be one of

         FILEPATH = File chooser dialog.
         PATH     = Directory chooser dialog.
         STRING   = Arbitrary string.
         BOOL     = Boolean ON/OFF checkbox.
         INTERNAL = No GUI entry (used for persistent variables).

       If <type> is INTERNAL, then the <value> is always written into the
       cache, replacing any values existing in the cache.  If it is not a
       cache variable, then this always writes into the current makefile.
       The FORCE option will overwrite the cache value removing any changes
       by the user.

       If PARENT_SCOPE is present, the variable will be set in the scope
       above the current scope.  Each new directory or function creates a new
       scope.  This command will set the value of a variable into the parent
       directory or calling function (whichever is applicable to the case at
       hand) If VALUE is not specified then the variable is removed from the
       parent scope.

         set(<variable> <value1> ... <valueN>)

       In this case <variable> is set to a semicolon separated list of
       values.

       <variable> can be an environment variable such as:

         set( ENV{PATH} /home/martink )

       in which case the environment variable will be set.

  set_directory_properties
       Set a property of the directory.

         set_directory_properties(PROPERTIES prop1 value1 prop2 value2)

       Set a property for the current directory and subdirectories.  If the
       property is not found, CMake will report an error.  The properties
       include: INCLUDE_DIRECTORIES, LINK_DIRECTORIES,
       INCLUDE_REGULAR_EXPRESSION, and ADDITIONAL_MAKE_CLEAN_FILES.

       ADDITIONAL_MAKE_CLEAN_FILES is a list of files that will be cleaned as
       a part of "make clean" stage.

  set_property
       Set a named property in a given scope.

         set_property(<GLOBAL                            |
                       DIRECTORY [dir]                   |
                       TARGET    [target1 [target2 ...]] |
                       SOURCE    [src1 [src2 ...]]       |
                       TEST      [test1 [test2 ...]]>
                      [APPEND]
                      PROPERTY <name> [value1 [value2 ...]])

       Set one property on zero or more objects of a scope.  The first
       argument determines the scope in which the property is set.  It must
       be one of the following:

       GLOBAL scope is unique and does not accept a name.

       DIRECTORY scope defaults to the current directory but another
       directory (already processed by CMake) may be named by full or
       relative path.

       TARGET scope may name zero or more existing targets.

       SOURCE scope may name zero or more source files.

       TEST scope may name zero or more existing tests.

       The required PROPERTY option is immediately followed by the name of
       the property to set.  Remaining arguments are used to compose the
       property value in the form of a semicolon-separated list.  If the
       APPEND option is given the list is appended to any existing property
       value.

  set_source_files_properties
       Source files can have properties that affect how they are built.

         set_source_files_properties(file1 file2 ...
                                     PROPERTIES prop1 value1
                                     prop2 value2 ...)

       Set properties on a file.  The syntax for the command is to list all
       the files you want to change, and then provide the values you want to
       set next.  You can make up your own properties as well.  The following
       are used by CMake.  The ABSTRACT flag (boolean) is used by some class
       wrapping commands.  If WRAP_EXCLUDE (boolean) is true then many
       wrapping commands will ignore this file.  If GENERATED (boolean) is
       true then it is not an error if this source file does not exist when
       it is added to a target.  Obviously, it must be created (presumably by
       a custom command) before the target is built.  If the HEADER_FILE_ONLY
       (boolean) property is true then the file is not compiled.  This is
       useful if you want to add extra non build files to an IDE.
       OBJECT_DEPENDS (string) adds dependencies to the object file.
       COMPILE_FLAGS (string) is passed to the compiler as additional command
       line arguments when the source file is compiled.  LANGUAGE (string)
       CXX|C will change the default compiler used to compile the source
       file.  The languages used need to be enabled in the PROJECT command.
       If SYMBOLIC (boolean) is set to true the build system will be informed
       that the source file is not actually created on disk but instead used
       as a symbolic name for a build rule.

  set_target_properties
       Targets can have properties that affect how they are built.

         set_target_properties(target1 target2 ...
                               PROPERTIES prop1 value1
                               prop2 value2 ...)

       Set properties on a target.  The syntax for the command is to list all
       the files you want to change, and then provide the values you want to
       set next.  You can use any prop value pair you want and extract it
       later with the GET_TARGET_PROPERTY command.

       Properties that affect the name of a target's output file are as
       follows.  The PREFIX and SUFFIX properties override the default target
       name prefix (such as "lib") and suffix (such as ".so").  IMPORT_PREFIX
       and IMPORT_SUFFIX are the equivalent properties for the import library
       corresponding to a DLL (for SHARED library targets).  OUTPUT_NAME sets
       the real name of a target when it is built and can be used to help
       create two targets of the same name even though CMake requires unique
       logical target names.  There is also a <CONFIG>_OUTPUT_NAME that can
       set the output name on a per-configuration basis.  <CONFIG>_POSTFIX
       sets a postfix for the real name of the target when it is built under
       the configuration named by <CONFIG> (in upper-case, such as
       "DEBUG_POSTFIX").  The value of this property is initialized when the
       target is created to the value of the variable CMAKE_<CONFIG>_POSTFIX
       (except for executable targets because earlier CMake versions which
       did not use this variable for executables).

       The LINK_FLAGS property can be used to add extra flags to the link
       step of a target.  LINK_FLAGS_<CONFIG> will add to the configuration
       <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.
       DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
       compiling sources in a shared library.  If not set here then it is set
       to target_EXPORTS by default (with some substitutions if the target is
       not a valid C identifier).  This is useful for headers to know whether
       they are being included from inside their library our outside to
       properly setup dllexport/dllimport decorations.  The COMPILE_FLAGS
       property sets additional compiler flags used to build sources within
       the target.  It may also be used to pass additional preprocessor
       definitions.

       The LINKER_LANGUAGE property is used to change the tool used to link
       an executable or shared library.  The default is set the language to
       match the files in the library.  CXX and C are common values for this
       property.

       For shared libraries VERSION and SOVERSION can be used to specify the
       build version and api version respectively.  When building or
       installing appropriate symlinks are created if the platform supports
       symlinks and the linker supports so-names.  If only one of both is
       specified the missing is assumed to have the same version number.  For
       executables VERSION can be used to specify the build version.  When
       building or installing appropriate symlinks are created if the
       platform supports symlinks.  For shared libraries and executables on
       Windows the VERSION attribute is parsed to extract a "major.minor"
       version number.  These numbers are used as the image version of the
       binary.

       There are a few properties used to specify RPATH rules.  INSTALL_RPATH
       is a semicolon-separated list specifying the rpath to use in installed
       targets (for platforms that support it).  INSTALL_RPATH_USE_LINK_PATH
       is a boolean that if set to true will append directories in the linker
       search path and outside the project to the INSTALL_RPATH.
       SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
       generation of an rpath allowing the target to run from the build tree.
       BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
       target in the build tree with the INSTALL_RPATH.  This takes
       precedence over SKIP_BUILD_RPATH and avoids the need for relinking
       before installation.  INSTALL_NAME_DIR is a string specifying the
       directory portion of the "install_name" field of shared libraries on
       Mac OSX to use in the installed targets.  When the target is created
       the values of the variables CMAKE_INSTALL_RPATH,
       CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH,
       CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to
       initialize these properties.

       PROJECT_LABEL can be used to change the name of the target in an IDE
       like visual studio.  VS_KEYWORD can be set to change the visual studio
       keyword, for example QT integration works better if this is set to
       Qt4VSv1.0.

       When a library is built CMake by default generates code to remove any
       existing library using all possible names.  This is needed to support
       libraries that switch between STATIC and SHARED by a user option.
       However when using OUTPUT_NAME to build a static and shared library of
       the same name using different logical target names the two targets
       will remove each other's files.  This can be prevented by setting the
       CLEAN_DIRECT_OUTPUT property to 1.

       The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
       way to specify CMake scripts to run before and after installing a
       target.  They are used only when the old INSTALL_TARGETS command is
       used to install the target.  Use the INSTALL command instead.

       The EXCLUDE_FROM_DEFAULT_BUILD property is used by the visual studio
       generators.  If it is set to 1 the target will not be part of the
       default build when you select "Build Solution".

  set_tests_properties
       Set a property of the tests.

         set_tests_properties(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)

       Set a property for the tests.  If the property is not found, CMake
       will report an error.  The properties include:

       WILL_FAIL: If set to true, this will invert the pass/fail flag of the
       test.

       PASS_REGULAR_EXPRESSION: If set, the test output will be checked
       against the specified regular expressions and at least one of the
       regular expressions has to match, otherwise the test will fail.

         Example: PASS_REGULAR_EXPRESSION "TestPassed;All ok"

       FAIL_REGULAR_EXPRESSION: If set, if the output will match to one of
       specified regular expressions, the test will fail.

         Example: PASS_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"

       Both PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION expect a list
       of regular expressions.


  site_name
       Set the given variable to the name of the computer.

         site_name(variable)


  source_group
       Define a grouping for sources in the makefile.

         source_group(name [REGULAR_EXPRESSION regex] [FILES src1 src2 ...])

       Defines a group into which sources will be placed in project files.
       This is mainly used to setup file tabs in Visual Studio.  Any file
       whose name is listed or matches the regular expression will be placed
       in this group.  If a file matches multiple groups, the LAST group that
       explicitly lists the file will be favored, if any.  If no group
       explicitly lists the file, the LAST group whose regular expression
       matches the file will be favored.

       The name of the group may contain backslashes to specify subgroups:

         source_group(outer\\inner ...)

       For backwards compatibility, this command is also supports the format:

         source_group(name regex)

  string
       String operations.

         string(REGEX MATCH <regular_expression>
                <output variable> <input> [<input>...])
         string(REGEX MATCHALL <regular_expression>
                <output variable> <input> [<input>...])
         string(REGEX REPLACE <regular_expression>
                <replace_expression> <output variable>
                <input> [<input>...])
         string(REPLACE <match_string>
                <replace_string> <output variable>
                <input> [<input>...])
         string(COMPARE EQUAL <string1> <string2> <output variable>)
         string(COMPARE NOTEQUAL <string1> <string2> <output variable>)
         string(COMPARE LESS <string1> <string2> <output variable>)
         string(COMPARE GREATER <string1> <string2> <output variable>)
         string(ASCII <number> [<number> ...] <output variable>)
         string(CONFIGURE <string1> <output variable>
                [@ONLY] [ESCAPE_QUOTES])
         string(TOUPPER <string1> <output variable>)
         string(TOLOWER <string1> <output variable>)
         string(LENGTH <string> <output variable>)
         string(SUBSTRING <string> <begin> <length> <output variable>)
         string(STRIP <string> <output variable>)
         string(RANDOM [LENGTH <length>] [ALPHABET <alphabet>]
                <output variable>)

       REGEX MATCH will match the regular expression once and store the match
       in the output variable.

       REGEX MATCHALL will match the regular expression as many times as
       possible and store the matches in the output variable as a list.

       REGEX REPLACE will match the regular expression as many times as
       possible and substitute the replacement expression for the match in
       the output.  The replace expression may refer to paren-delimited
       subexpressions of the match using \1, \2, ..., \9.  Note that two
       backslashes (\\1) are required in CMake code to get a backslash
       through argument parsing.

       REPLACE will replace all occurrences of match_string in the input with
       replace_string and store the result in the output.

       COMPARE EQUAL/NOTEQUAL/LESS/GREATER will compare the strings and store
       true or false in the output variable.

       ASCII will convert all numbers into corresponding ASCII characters.

       CONFIGURE will transform a string like CONFIGURE_FILE transforms a
       file.

       TOUPPER/TOLOWER will convert string to upper/lower characters.

       LENGTH will return a given string's length.

       SUBSTRING will return a substring of a given string.

       STRIP will return a substring of a given string with leading and
       trailing spaces removed.

       RANDOM will return a random string of given length consisting of
       characters from the given alphabet.  Default length is 5 characters
       and default alphabet is all numbers and upper and lower case letters.

       The following characters have special meaning in regular expressions:

          ^         Matches at beginning of a line
          $         Matches at end of a line
          .         Matches any single character
          [ ]       Matches any character(s) inside the brackets
          [^ ]      Matches any character(s) not inside the brackets
           -        Matches any character in range on either side of a dash
          *         Matches preceding pattern zero or more times
          +         Matches preceding pattern one or more times
          ?         Matches preceding pattern zero or once only
          |         Matches a pattern on either side of the |
          ()        Saves a matched subexpression, which can be referenced in the REGEX REPLACE operation. Additionally it is saved in the special CMake variables CMAKE_MATCH_(0..9).

  target_link_libraries
       Link a target to given libraries.

         target_link_libraries(<target> [lib1 [lib2 [...]]]
                               [[debug|optimized|general] <lib>] ...)

       Specify a list of libraries to be linked into the specified target.
       If any library name matches that of a target in the current project a
       dependency will automatically be added in the build system to make
       sure the library being linked is up-to-date before the target links.

       A "debug", "optimized", or "general" keyword indicates that the
       library immediately following it is to be used only for the
       corresponding build configuration.  The "debug" keyword corresponds to
       the Debug configuration.  The "optimized" keyword corresponds to all
       other configurations.  The "general" keyword corresponds to all
       configurations, and is purely optional (assumed if omitted).  Higher
       granularity may be achieved for per-configuration rules by creating
       and linking to IMPORTED library targets.  See the IMPORTED mode of the
       add_library command for more information.

       Library dependencies are transitive by default.  When this target is
       linked into another target then the libraries linked to this target
       will appear on the link line for the other target too.  See the
       LINK_INTERFACE_LIBRARIES target property to override the set of
       transitive link dependencies for a target.

         target_link_libraries(<target> LINK_INTERFACE_LIBRARIES
                               [[debug|optimized|general] <lib>] ...)

       The LINK_INTERFACE_LIBRARIES mode appends the libraries to the
       LINK_INTERFACE_LIBRARIES and LINK_INTERFACE_LIBRARIES_DEBUG target
       properties instead of using them for linking.  Libraries specified as
       "debug" are appended to the the LINK_INTERFACE_LIBRARIES_DEBUG
       property.  Libraries specified as "optimized" are appended to the the
       LINK_INTERFACE_LIBRARIES property.  Libraries specified as "general"
       (or without any keyword) are appended to both properties.

  try_compile
       Try compiling some code.

         try_compile(RESULT_VAR bindir srcdir
                     projectName <targetname> [CMAKE_FLAGS <Flags>]
                     [OUTPUT_VARIABLE var])

       Try compiling a program.  In this form, srcdir should contain a
       complete CMake project with a CMakeLists.txt file and all sources.
       The bindir and srcdir will not be deleted after this command is run.
       If <target name> is specified then build just that target otherwise
       the all or ALL_BUILD target is built.

         try_compile(RESULT_VAR bindir srcfile
                     [CMAKE_FLAGS <Flags>]
                     [COMPILE_DEFINITIONS <flags> ...]
                     [OUTPUT_VARIABLE var]
                     [COPY_FILE <filename> )

       Try compiling a srcfile.  In this case, the user need only supply a
       source file.  CMake will create the appropriate CMakeLists.txt file to
       build the source.  If COPY_FILE is used, the compiled file will be
       copied to the given file.

       In this version all files in bindir/CMakeFiles/CMakeTmp, will be
       cleaned automatically, for debugging a --debug-trycompile can be
       passed to cmake to avoid the clean.  Some extra flags that can be
       included are, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, and
       LINK_LIBRARIES.  COMPILE_DEFINITIONS are -Ddefinition that will be
       passed to the compile line.  try_compile creates a CMakeList.txt file
       on the fly that looks like this:

         add_definitions( <expanded COMPILE_DEFINITIONS from calling cmake>)
         include_directories(${INCLUDE_DIRECTORIES})
         link_directories(${LINK_DIRECTORIES})
         add_executable(cmTryCompileExec sources)
         target_link_libraries(cmTryCompileExec ${LINK_LIBRARIES})

       In both versions of the command, if OUTPUT_VARIABLE is specified, then
       the output from the build process is stored in the given variable.
       Return the success or failure in RESULT_VAR.  CMAKE_FLAGS can be used
       to pass -DVAR:TYPE=VALUE flags to the cmake that is run during the
       build.

  try_run
       Try compiling and then running some code.

         try_run(RUN_RESULT_VAR COMPILE_RESULT_VAR
                 bindir srcfile [CMAKE_FLAGS <Flags>]
                 [COMPILE_DEFINITIONS <flags>]
                 [COMPILE_OUTPUT_VARIABLE comp]
                 [RUN_OUTPUT_VARIABLE run]
                 [OUTPUT_VARIABLE var]
                 [ARGS <arg1> <arg2>...])

       Try compiling a srcfile.  Return TRUE or FALSE for success or failure
       in COMPILE_RESULT_VAR.  Then if the compile succeeded, run the
       executable and return its exit code in RUN_RESULT_VAR.  If the
       executable was built, but failed to run, then RUN_RESULT_VAR will be
       set to FAILED_TO_RUN.  COMPILE_OUTPUT_VARIABLE specifies the variable
       where the output from the compile step goes.  RUN_OUTPUT_VARIABLE
       specifies the variable where the output from the running executable
       goes.

       For compatibility reasons OUTPUT_VARIABLE is still supported, which
       gives you the output from the compile and run step combined.

       

       Cross compiling issues

       When cross compiling, the executable compiled in the first step
       usually cannot be run on the build host.  try_run() checks the
       CMAKE_CROSSCOMPILING variable to detect whether CMake is in
       crosscompiling mode.  If that's the case, it will still try to compile
       the executable, but it will not try to run the executable.  Instead it
       will create cache variables which must be filled by the user or by
       presetting them in some CMake script file to the values the executable
       would have produced if it would have been run on its actual target
       platform.  These variables are RUN_RESULT_VAR (explanation see above)
       and if RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) was used, an
       additional cache variable
       RUN_RESULT_VAR__COMPILE_RESULT_VAR__TRYRUN_OUTPUT.This is intended to
       hold stdout and stderr from the executable.

       In order to make cross compiling your project easier, use try_run only
       if really required.  If you use try_run, use RUN_OUTPUT_VARIABLE (or
       OUTPUT_VARIABLE) only if really required.  Using them will require
       that when crosscompiling, the cache variables will have to be set
       manually to the output of the executable.  You can also "guard" the
       calls to try_run with if(CMAKE_CROSSCOMPILING) and provide an
       easy-to-preset alternative for this case.


  variable_watch
       Watch the CMake variable for change.

         variable_watch(<variable name> [<command to execute>])

       If the specified variable changes, the message will be printed about
       the variable being changed.  If the command is specified, the command
       will be executed.  The command will receive the following arguments:
       COMMAND(<variable> <access> <value> <current list file> <stack>)

  while
       Evaluate a group of commands while a condition is true

         while(condition)
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endwhile(condition)

       All commands between while and the matching endwhile are recorded
       without being invoked.  Once the endwhile is evaluated, the recorded
       list of commands is invoked as long as the condition is true.  The
       condition is evaluated using the same logic as the if command.

------------------------------------------------------------------------------
Properties

  CMake Properties - Properties supported by CMake, the Cross-Platform Makefile Generator.

This is the documentation for the properties supported by CMake.  Properties
can have different scopes.  They can either be assigned to a source file, a
directory, a target or globally to CMake.  By modifying the values of
properties the behaviour of the build system can be customized.

------------------------------------------------------------------------------
Properties of Global Scope

  ALLOW_DUPLICATE_CUSTOM_TARGETS
       Allow duplicate custom targets to be created.

       Normally CMake requires that all targets built in a project have
       globally unique logical names (see policy CMP0002).  This is necessary
       to generate meaningful project file names in Xcode and VS IDE
       generators.  It also allows the target names to be referenced
       unambiguously.

       Makefile generators are capable of supporting duplicate custom target
       names.  For projects that care only about Makefile generators and do
       not wish to support Xcode or VS IDE generators, one may set this
       property to true to allow duplicate custom targets.  The property
       allows multiple add_custom_target command calls in different
       directories to specify the same target name.  However, setting this
       property will cause non-Makefile generators to produce an error and
       refuse to generate the project.

  DISABLED_FEATURES
       List of features which are disabled during the CMake run.

       List of features which are disabled during the CMake run.  Be default
       it contains the names of all packages which were not found.  This is
       determined using the <NAME>_FOUND variables.  Packages which are
       searched QUIET are not listed.  A project can add its own features to
       this list.This property is used by the macros in FeatureSummary.cmake.

  ENABLED_FEATURES
       List of features which are enabled during the CMake run.

       List of features which are enabled during the CMake run.  Be default
       it contains the names of all packages which were found.  This is
       determined using the <NAME>_FOUND variables.  Packages which are
       searched QUIET are not listed.  A project can add its own features to
       this list.This property is used by the macros in FeatureSummary.cmake.

  ENABLED_LANGUAGES
       Read-only property that contains the list of currently enabled
       languages

       Set to list of currently enabled lanauges.

  FIND_LIBRARY_USE_LIB64_PATHS
       Whether FIND_LIBRARY should automatically search lib64 directories.

       FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether the
       FIND_LIBRARY command should automatically search the lib64 variant of
       directories called lib in the search path when building 64-bit
       binaries.

  GLOBAL_DEPENDS_DEBUG_MODE
       Enable global target dependency graph debug mode.

       CMake automatically analyzes the global inter-target dependency graph
       at the beginning of native build system generation.  This property
       causes it to display details of its analysis to stderr.

  IN_TRY_COMPILE
       Read-only property that is true during a try-compile configuration.

       True when building a project inside a TRY_COMPILE or TRY_RUN command.

  PACKAGES_FOUND
       List of packages which were found during the CMake run.

       List of packages which were found during the CMake run.  Whether a
       package has been found is determined using the <NAME>_FOUND variables.

  PACKAGES_NOT_FOUND
       List of packages which were not found during the CMake run.

       List of packages which were not found during the CMake run.  Whether a
       package has been found is determined using the <NAME>_FOUND variables.

  REPORT_UNDEFINED_PROPERTIES
       If set, report any undefined properties to this file.

       If this property is set to a filename then when CMake runs it will
       report any properties or variables that were accessed but not defined
       into the filename specified in this property.

  TARGET_ARCHIVES_MAY_BE_SHARED_LIBS
       Set if shared libraries may be named like archives.

       On AIX shared libraries may be named "lib<name>.a".  This property is
       set to true on such platforms.

  TARGET_SUPPORTS_SHARED_LIBS
       Does the target platform support shared libraries.

       TARGET_SUPPORTS_SHARED_LIBS is a boolean specifying whether the target
       platform supports shared libraries.  Basically all current general
       general purpose OS do so, the exception are usually embedded systems
       with no or special OSs.

  __CMAKE_DELETE_CACHE_CHANGE_VARS_
       Internal property

       Used to detect compiler changes, Do not set.

------------------------------------------------------------------------------
Properties on Directories

  ADDITIONAL_MAKE_CLEAN_FILES
       Additional files to clean during the make clean stage.

       A list of files that will be cleaned as a part of the "make clean"
       stage.

  CACHE_VARIABLES
       List of cache variables available in the current directory.

       This read-only property specifies the list of CMake cache variables
       currently defined.  It is intended for debugging purposes.

  CLEAN_NO_CUSTOM
       Should the output of custom commands be left.

       If this is true then the outputs of custom commands for this directory
       will not be removed during the "make clean" stage.

  COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a directory's sources.

       The COMPILE_DEFINITIONS property may be set to a list of preprocessor
       definitions using the syntax VAR or VAR=value.  Function-style
       definitions are not supported.  CMake will automatically escape the
       value correctly for the native build system (note that CMake language
       syntax may require escapes to specify some values).  This property may
       be set on a per-configuration basis using the name
       COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case name (ex.
       "COMPILE_DEFINITIONS_DEBUG").  This property will be initialized in
       each directory by its value in the directory's parent.

       CMake will automatically drop some definitions that are not supported
       by the native build tool.  The VS6 IDE does not support definitions
       with values (but NMake does).

       Dislaimer: Most native build tools have poor support for escaping
       certain values.  CMake has work-arounds for many cases but some values
       may just not be possible to pass correctly.  If a value does not seem
       to be escaped correctly, do not attempt to work-around the problem by
       adding escape sequences to the value.  Your work-around may break in a
       future version of CMake that has improved escape support.  Instead
       consider defining the macro in a (configured) header file.  Then
       report the limitation.

  COMPILE_DEFINITIONS_<CONFIG>
       Per-configuration preprocessor definitions in a directory.

       This is the configuration-specific version of COMPILE_DEFINITIONS.
       This property will be initialized in each directory by its value in
       the directory's parent.


  DEFINITIONS
       For CMake 2.4 compatibility only.  Use COMPILE_DEFINITIONS instead.

       This read-only property specifies the list of flags given so far to
       the add_definitions command.  It is intended for debugging purposes.
       Use the COMPILE_DEFINITIONS instead.

  EXCLUDE_FROM_ALL
       Exclude the directory from the all target of its parent.

       A property on a directory that indicates if its targets are excluded
       from the default build target.  If it is not, then with a Makefile for
       example typing make will cause the targets to be built.  The same
       concept applies to the default build of other generators.

  IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
       Specify #include line transforms for dependencies in a directory.

       This property specifies rules to transform macro-like #include lines
       during implicit dependency scanning of C and C++ source files.  The
       list of rules must be semicolon-separated with each entry of the form
       "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency
       scanning occurrences of A_MACRO(...) on #include lines will be
       replaced by the value given with the macro argument substituted for
       '%'.  For example, the entry

         MYDIR(%)=<mydir/%>

       will convert lines of the form

         #include MYDIR(myheader.h)

       to

         #include <mydir/myheader.h>

       allowing the dependency to be followed.

       This property applies to sources in all targets within a directory.
       The property value is initialized in each directory by its value in
       the directory's parent.

  INCLUDE_DIRECTORIES
       List of preprocessor include file search directories.

       This read-only property specifies the list of directories given so far
       to the include_directories command.  It is intended for debugging
       purposes.

  INCLUDE_REGULAR_EXPRESSION
       Include file scanning regular expression.

       This read-only property specifies the regular expression used during
       dependency scanning to match include files that should be followed.
       See the include_regular_expression command.

  LINK_DIRECTORIES
       List of linker search directories.

       This read-only property specifies the list of directories given so far
       to the link_directories command.  It is intended for debugging
       purposes.

  LISTFILE_STACK
       The current stack of listfiles being processed.

       This property is mainly useful when trying to debug errors in your
       CMake scripts.  It returns a list of what list files are currently
       being processed, in order.  So if one listfile does an INCLUDE command
       then that is effectively pushing the included listfile onto the stack.

  MACROS
       List of macro commands available in the current directory.

       This read-only property specifies the list of CMake macros currently
       defined.  It is intended for debugging purposes.  See the macro
       command.

  PARENT_DIRECTORY
       Source directory that added current subdirectory.

       This read-only property specifies the source directory that added the
       current source directory as a subdirectory of the build.  In the
       top-level directory the value is the empty-string.

  TEST_INCLUDE_FILE
       A cmake file that will be included when ctest is run.

       If you specify TEST_INCLUDE_FILE, that file will be included and
       processed when ctest is run on the directory.

  VARIABLES
       List of variables defined in the current directory.

       This read-only property specifies the list of CMake variables
       currently defined.  It is intended for debugging purposes.

------------------------------------------------------------------------------
Properties on Targets

  ARCHIVE_OUTPUT_DIRECTORY
       Output directory in which to build ARCHIVE target files.

       This property specifies the directory into which archive target files
       should be built.  There are three kinds of target files that may be
       built: archive, library, and runtime.  Executables are always treated
       as runtime targets.  Static libraries are always treated as archive
       targets.  Module libraries are always treated as library targets.  For
       non-DLL platforms shared libraries are treated as library targets.
       For DLL platforms the DLL part of a shared library is treated as a
       runtime target and the corresponding import library is treated as an
       archive target.  All Windows-based systems including Cygwin are DLL
       platforms.  This property is initialized by the value of the variable
       CMAKE_ARCHIVE_OUTPUT_DIRECTORY if it is set when a target is created.

  BUILD_WITH_INSTALL_RPATH
       Should build tree targets have install tree rpaths.

       BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
       target in the build tree with the INSTALL_RPATH.  This takes
       precedence over SKIP_BUILD_RPATH and avoids the need for relinking
       before installation.

  CLEAN_DIRECT_OUTPUT
       Do not delete other variants of this target.

       When a library is built CMake by default generates code to remove any
       existing library using all possible names.  This is needed to support
       libraries that switch between STATIC and SHARED by a user option.
       However when using OUTPUT_NAME to build a static and shared library of
       the same name using different logical target names the two targets
       will remove each other's files.  This can be prevented by setting the
       CLEAN_DIRECT_OUTPUT property to 1.

  COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a target's sources.

       The COMPILE_DEFINITIONS property may be set to a list of preprocessor
       definitions using the syntax VAR or VAR=value.  Function-style
       definitions are not supported.  CMake will automatically escape the
       value correctly for the native build system (note that CMake language
       syntax may require escapes to specify some values).  This property may
       be set on a per-configuration basis using the name
       COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case name (ex.
       "COMPILE_DEFINITIONS_DEBUG").

       CMake will automatically drop some definitions that are not supported
       by the native build tool.  The VS6 IDE does not support definitions
       with values (but NMake does).

       Dislaimer: Most native build tools have poor support for escaping
       certain values.  CMake has work-arounds for many cases but some values
       may just not be possible to pass correctly.  If a value does not seem
       to be escaped correctly, do not attempt to work-around the problem by
       adding escape sequences to the value.  Your work-around may break in a
       future version of CMake that has improved escape support.  Instead
       consider defining the macro in a (configured) header file.  Then
       report the limitation.

  COMPILE_DEFINITIONS_<CONFIG>
       Per-configuration preprocessor definitions on a target.

       This is the configuration-specific version of COMPILE_DEFINITIONS.

  COMPILE_FLAGS
       Additional flags to use when compiling this target's sources.

       The COMPILE_FLAGS property sets additional compiler flags used to
       build sources within the target.  Use COMPILE_DEFINITIONS to pass
       additional preprocessor definitions.

  DEBUG_POSTFIX
       A postfix that will be applied to this target when build debug.

       A property on a target that specifies a postfix to add to the target
       name when built in debug mode.  For example "foo.dll" versus
       "fooD.dll".  Ignored for Mac Frameworks and App Bundles.

  DEFINE_SYMBOL
       Define a symbol when compiling this target's sources.

       DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
       compiling sources in a shared library.  If not set here then it is set
       to target_EXPORTS by default (with some substitutions if the target is
       not a valid C identifier).  This is useful for headers to know whether
       they are being included from inside their library our outside to
       properly setup dllexport/dllimport decorations.

  ENABLE_EXPORTS
       Specify whether an executable exports symbols for loadable modules.

       Normally an executable does not export any symbols because it is the
       final program.  It is possible for an executable to export symbols to
       be used by loadable modules.  When this property is set to true CMake
       will allow other targets to "link" to the executable with the
       TARGET_LINK_LIBRARIES command.  On all platforms a target-level
       dependency on the executable is created for targets that link to it.
       For non-DLL platforms the link rule is simply ignored since the
       dynamic loader will automatically bind symbols when the module is
       loaded.  For DLL platforms an import library will be created for the
       exported symbols and then used for linking.  All Windows-based systems
       including Cygwin are DLL platforms.

  EXCLUDE_FROM_ALL
       Exclude the target from the all target.

       A property on a target that indicates if the target is excluded from
       the default build target.  If it is not, then with a Makefile for
       example typing make will cause this target to be built.  The same
       concept applies to the default build of other generators.  Installing
       a target with EXCLUDE_FROM_ALL set to true has undefined behavior.

  EchoString
       A message to be displayed when the target is built.

       A message to display on some generators (such as makefiles) when the
       target is built.

  FRAMEWORK
       This target is a framework on the Mac.

       If a shared library target has this property set to true it will be
       built as a framework when built on the mac.  It will have the
       directory structure required for a framework and will be suitable to
       be used with the -framework option

  Fortran_MODULE_DIRECTORY
       Specify output directory for Fortran modules provided by the target.

       If the target contains Fortran source files that provide modules and
       the compiler supports a module output directory this specifies the
       directory in which the modules will be placed.  When this property is
       not set the modules will be placed in the build directory
       corresponding to the target's source directory.  If the variable
       CMAKE_Fortran_MODULE_DIRECTORY is set when a target is created its
       value is used to initialize this property.

  GENERATOR_FILE_NAME
       Generator's file for this target.

       An internal property used by some generators to record the name of
       project or dsp file associated with this target.

  HAS_CXX
       Force a target to use the CXX linker.

       Setting HAS_CXX on a target will force the target to use the C++
       linker (and C++ runtime libraries) for linking even if the target has
       no C++ code in it.

  IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
       Specify #include line transforms for dependencies in a target.

       This property specifies rules to transform macro-like #include lines
       during implicit dependency scanning of C and C++ source files.  The
       list of rules must be semicolon-separated with each entry of the form
       "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency
       scanning occurrences of A_MACRO(...) on #include lines will be
       replaced by the value given with the macro argument substituted for
       '%'.  For example, the entry

         MYDIR(%)=<mydir/%>

       will convert lines of the form

         #include MYDIR(myheader.h)

       to

         #include <mydir/myheader.h>

       allowing the dependency to be followed.

       This property applies to sources in the target on which it is set.

  IMPORTED
       Read-only indication of whether a target is IMPORTED.

       The boolean value of this property is true for targets created with
       the IMPORTED option to add_executable or add_library.  It is false for
       targets built within the project.

  IMPORTED_CONFIGURATIONS
       Configurations provided for an IMPORTED target.

       Lists configuration names available for an IMPORTED target.  The names
       correspond to configurations defined in the project from which the
       target is imported.  If the importing project uses a different set of
       configurations the names may be mapped using the
       MAP_IMPORTED_CONFIG_<CONFIG> property.  Ignored for non-imported
       targets.

  IMPORTED_IMPLIB
       Full path to the import library for an IMPORTED target.

       Specifies the location of the ".lib" part of a windows DLL.  Ignored
       for non-imported targets.

  IMPORTED_IMPLIB_<CONFIG>
       Per-configuration version of IMPORTED_IMPLIB property.

       This property is used when loading settings for the <CONFIG>
       configuration of an imported target.  Configuration names correspond
       to those provided by the project from which the target is imported.

  IMPORTED_LINK_DEPENDENT_LIBRARIES
       Dependent shared libraries of an imported shared library.

       Shared libraries may be linked to other shared libraries as part of
       their implementation.  On some platforms the linker searches for the
       dependent libraries of shared libraries they are including in the
       link.  This property lists the dependent shared libraries of an
       imported library.  The list should be disjoint from the list of
       interface libraries in the IMPORTED_LINK_INTERFACE_LIBRARIES property.
       On platforms requiring dependent shared libraries to be found at link
       time CMake uses this list to add appropriate files or paths to the
       link command line.  Ignored for non-imported targets.

  IMPORTED_LINK_DEPENDENT_LIBRARIES_<CONFIG>
       Per-configuration version of IMPORTED_LINK_DEPENDENT_LIBRARIES.

       This property is used when loading settings for the <CONFIG>
       configuration of an imported target.  Configuration names correspond
       to those provided by the project from which the target is imported.
       If set, this property completely overrides the generic property for
       the named configuration.

  IMPORTED_LINK_INTERFACE_LIBRARIES
       Transitive link interface of an IMPORTED target.

       Lists libraries whose interface is included when an IMPORTED library
       target is linked to another target.  The libraries will be included on
       the link line for the target.  Unlike the LINK_INTERFACE_LIBRARIES
       property, this property applies to all imported target types,
       including STATIC libraries.  This property is ignored for non-imported
       targets.

  IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
       Per-configuration version of IMPORTED_LINK_INTERFACE_LIBRARIES.

       This property is used when loading settings for the <CONFIG>
       configuration of an imported target.  Configuration names correspond
       to those provided by the project from which the target is imported.
       If set, this property completely overrides the generic property for
       the named configuration.

  IMPORTED_LOCATION
       Full path to the main file on disk for an IMPORTED target.

       Specifies the location of an IMPORTED target file on disk.  For
       executables this is the location of the executable file.  For bundles
       on OS X this is the location of the executable file inside
       Contents/MacOS under the application bundle folder.  For static
       libraries and modules this is the location of the library or module.
       For shared libraries on non-DLL platforms this is the location of the
       shared library.  For frameworks on OS X this is the location of the
       library file symlink just inside the framework folder.  For DLLs this
       is the location of the ".dll" part of the library.  For UNKNOWN
       libraries this is the location of the file to be linked.  Ignored for
       non-imported targets.

  IMPORTED_LOCATION_<CONFIG>
       Per-configuration version of IMPORTED_LOCATION property.

       This property is used when loading settings for the <CONFIG>
       configuration of an imported target.  Configuration names correspond
       to those provided by the project from which the target is imported.

  IMPORTED_SONAME
       The "soname" of an IMPORTED target of shared library type.

       Specifies the "soname" embedded in an imported shared library.  This
       is meaningful only on platforms supporting the feature.  Ignored for
       non-imported targets.

  IMPORTED_SONAME_<CONFIG>
       Per-configuration version of IMPORTED_SONAME property.

       This property is used when loading settings for the <CONFIG>
       configuration of an imported target.  Configuration names correspond
       to those provided by the project from which the target is imported.

  IMPORT_PREFIX
       What comes before the import library name.

       Similar to the target property PREFIX, but used for import libraries
       (typically corresponding to a DLL) instead of regular libraries.  A
       target property that can be set to override the prefix (such as "lib")
       on an import library name.

  IMPORT_SUFFIX
       What comes after the import library name.

       Similar to the target property SUFFIX, but used for import libraries
       (typically corresponding to a DLL) instead of regular libraries.  A
       target property that can be set to override the suffix (such as
       ".lib") on an import library name.

  INSTALL_NAME_DIR
       Mac OSX directory name for installed targets.

       INSTALL_NAME_DIR is a string specifying the directory portion of the
       "install_name" field of shared libraries on Mac OSX to use in the
       installed targets.

  INSTALL_RPATH
       The rpath to use for installed targets.

       A semicolon-separated list specifying the rpath to use in installed
       targets (for platforms that support it).

  INSTALL_RPATH_USE_LINK_PATH
       Add paths to linker search and installed rpath.

       INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will
       append directories in the linker search path and outside the project
       to the INSTALL_RPATH.

  LIBRARY_OUTPUT_DIRECTORY
       Output directory in which to build LIBRARY target files.

       This property specifies the directory into which library target files
       should be built.  There are three kinds of target files that may be
       built: archive, library, and runtime.  Executables are always treated
       as runtime targets.  Static libraries are always treated as archive
       targets.  Module libraries are always treated as library targets.  For
       non-DLL platforms shared libraries are treated as library targets.
       For DLL platforms the DLL part of a shared library is treated as a
       runtime target and the corresponding import library is treated as an
       archive target.  All Windows-based systems including Cygwin are DLL
       platforms.  This property is initialized by the value of the variable
       CMAKE_LIBRARY_OUTPUT_DIRECTORY if it is set when a target is created.

  LINKER_LANGUAGE
       What tool to use for linking, based on language.

       The LINKER_LANGUAGE property is used to change the tool used to link
       an executable or shared library.  The default is set the language to
       match the files in the library.  CXX and C are common values for this
       property.

  LINK_FLAGS
       Additional flags to use when linking this target.

       The LINK_FLAGS property can be used to add extra flags to the link
       step of a target.  LINK_FLAGS_<CONFIG> will add to the configuration
       <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.

  LINK_FLAGS_<CONFIG>
       Per-configuration linker flags for a target.

       This is the configuration-specific version of LINK_FLAGS.

  LINK_INTERFACE_LIBRARIES
       List public interface libraries for a shared library or executable.

       By default linking to a shared library target transitively links to
       targets with which the library itself was linked.  For an executable
       with exports (see the ENABLE_EXPORTS property) no default transitive
       link dependencies are used.  This property replaces the default
       transitive link dependencies with an explict list.  When the target is
       linked into another target the libraries listed (and recursively their
       link interface libraries) will be provided to the other target also.
       If the list is empty then no transitive link dependencies will be
       incorporated when this target is linked into another target even if
       the default set is non-empty.  This property is ignored for STATIC
       libraries.

  LINK_INTERFACE_LIBRARIES_<CONFIG>
       Per-configuration list of public interface libraries for a target.

       This is the configuration-specific version of
       LINK_INTERFACE_LIBRARIES.  If set, this property completely overrides
       the generic property for the named configuration.

  LINK_SEARCH_END_STATIC
       End a link line such that static system libraries are used.

       Some linkers support switches such as -Bstatic and -Bdynamic to
       determine whether to use static or shared libraries for -lXXX options.
       CMake uses these options to set the link type for libraries whose full
       paths are not known or (in some cases) are in implicit link
       directories for the platform.  By default the linker search type is
       left at -Bdynamic by the end of the library list.  This property
       switches the final linker search type to -Bstatic.

  LOCATION
       Deprecated.  Use LOCATION_<CONFIG> or avoid altogether.

       This property is provided for compatibility with CMake 2.4 and below.
       It was meant to get the location of an executable target's output file
       for use in add_custom_command.  In CMake 2.6 and above
       add_custom_command automatically recognizes a target name in its
       COMMAND and DEPENDS options and computes the target location.
       Therefore this property need not be used.  This property is not
       defined for IMPORTED targets because they were not available in CMake
       2.4 or below anyway.

  LOCATION_<CONFIG>
       Read-only property providing a target location on disk.

       A read-only property that indicates where a target's main file is
       located on disk for the configuration <CONFIG>.  The property is
       defined only for library and executable targets.

  MACOSX_BUNDLE
       Build an executable as an application bundle on Mac OS X.

       When this property is set to true the executable when built on Mac OS
       X will be created as an application bundle.  This makes it a GUI
       executable that can be launched from the Finder.  See the
       MACOSX_BUNDLE_INFO_PLIST target property for information about
       creation of the Info.plist file for the application bundle.

  MACOSX_BUNDLE_INFO_PLIST
       Specify a custom Info.plist template for a Mac OS X App Bundle.

       An executable target with MACOSX_BUNDLE enabled will be built as an
       application bundle on Mac OS X.  By default its Info.plist file is
       created by configuring a template called MacOSXBundleInfo.plist.in
       located in the CMAKE_MODULE_PATH.  This property specifies an
       alternative template file name which may be a full path.

       The following target properties may be set to specify content to be
       configured into the file:

         MACOSX_BUNDLE_INFO_STRING
         MACOSX_BUNDLE_ICON_FILE
         MACOSX_BUNDLE_GUI_IDENTIFIER
         MACOSX_BUNDLE_LONG_VERSION_STRING
         MACOSX_BUNDLE_BUNDLE_NAME
         MACOSX_BUNDLE_SHORT_VERSION_STRING
         MACOSX_BUNDLE_BUNDLE_VERSION
         MACOSX_BUNDLE_COPYRIGHT

       CMake variables of the same name may be set to affect all targets in a
       directory that do not have each specific property set.  If a custom
       Info.plist is specified by this property it may of course hard-code
       all the settings instead of using the target properties.

  MACOSX_FRAMEWORK_INFO_PLIST
       Specify a custom Info.plist template for a Mac OS X Framework.

       An library target with FRAMEWORK enabled will be built as a framework
       on Mac OS X.  By default its Info.plist file is created by configuring
       a template called MacOSXFrameworkInfo.plist.in located in the
       CMAKE_MODULE_PATH.  This property specifies an alternative template
       file name which may be a full path.

       The following target properties may be set to specify content to be
       configured into the file:

         MACOSX_FRAMEWORK_ICON_FILE
         MACOSX_FRAMEWORK_IDENTIFIER
         MACOSX_FRAMEWORK_SHORT_VERSION_STRING
         MACOSX_FRAMEWORK_BUNDLE_VERSION

       CMake variables of the same name may be set to affect all targets in a
       directory that do not have each specific property set.  If a custom
       Info.plist is specified by this property it may of course hard-code
       all the settings instead of using the target properties.

  MAP_IMPORTED_CONFIG_<CONFIG>
       Map from project configuration to IMPORTED target's configuration.

       List configurations of an imported target that may be used for the
       current project's <CONFIG> configuration.  Targets imported from
       another project may not provide the same set of configuration names
       available in the current project.  Setting this property tells CMake
       what imported configurations are suitable for use when building the
       <CONFIG> configuration.  The first configuration in the list found to
       be provided by the imported target is selected.  If no matching
       configurations are available the imported target is considered to be
       not found.  This property is ignored for non-imported targets.

  OUTPUT_NAME
       Sets the real name of a target when it is built.

       Sets the real name of a target when it is built and can be used to
       help create two targets of the same name even though CMake requires
       unique logical target names.  There is also a <CONFIG>_OUTPUT_NAME
       that can set the output name on a per-configuration basis.

  POST_INSTALL_SCRIPT
       Deprecated install support.

       The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
       way to specify CMake scripts to run before and after installing a
       target.  They are used only when the old INSTALL_TARGETS command is
       used to install the target.  Use the INSTALL command instead.

  PREFIX
       What comes before the library name.

       A target property that can be set to override the prefix (such as
       "lib") on a library name.

  PRE_INSTALL_SCRIPT
       Deprecated install support.

       The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
       way to specify CMake scripts to run before and after installing a
       target.  They are used only when the old INSTALL_TARGETS command is
       used to install the target.  Use the INSTALL command instead.

  PRIVATE_HEADER
       Specify private header files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate
       frameworks on OS X and normal shared libraries on other platforms.
       This property may be set to a list of header files to be placed in the
       PrivateHeaders directory inside the framework folder.  On non-Apple
       platforms these headers may be installed using the PRIVATE_HEADER
       option to the install(TARGETS) command.

  PUBLIC_HEADER
       Specify public header files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate
       frameworks on OS X and normal shared libraries on other platforms.
       This property may be set to a list of header files to be placed in the
       Headers directory inside the framework folder.  On non-Apple platforms
       these headers may be installed using the PUBLIC_HEADER option to the
       install(TARGETS) command.

  RESOURCE
       Specify resource files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate
       frameworks on OS X and normal shared libraries on other platforms.
       This property may be set to a list of files to be placed in the
       Resources directory inside the framework folder.  On non-Apple
       platforms these files may be installed using the RESOURCE option to
       the install(TARGETS) command.

  RUNTIME_OUTPUT_DIRECTORY
       Output directory in which to build RUNTIME target files.

       This property specifies the directory into which runtime target files
       should be built.  There are three kinds of target files that may be
       built: archive, library, and runtime.  Executables are always treated
       as runtime targets.  Static libraries are always treated as archive
       targets.  Module libraries are always treated as library targets.  For
       non-DLL platforms shared libraries are treated as library targets.
       For DLL platforms the DLL part of a shared library is treated as a
       runtime target and the corresponding import library is treated as an
       archive target.  All Windows-based systems including Cygwin are DLL
       platforms.  This property is initialized by the value of the variable
       CMAKE_RUNTIME_OUTPUT_DIRECTORY if it is set when a target is created.

  SKIP_BUILD_RPATH
       Should rpaths be used for the build tree.

       SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
       generation of an rpath allowing the target to run from the build tree.

  SOURCES
       Source names specified for a target.

       Read-only list of sources specified for a target.  The names returned
       are suitable for passing to the set_source_files_properties command.

  SOVERSION
       What version number is this target.

       For shared libraries VERSION and SOVERSION can be used to specify the
       build version and api version respectively.  When building or
       installing appropriate symlinks are created if the platform supports
       symlinks and the linker supports so-names.  If only one of both is
       specified the missing is assumed to have the same version number.  For
       shared libraries and executables on Windows the VERSION attribute is
       parsed to extract a "major.minor" version number.  These numbers are
       used as the image version of the binary.

  STATIC_LIBRARY_FLAGS
       Extra flags to use when linking static libraries.

       Extra flags to use when linking a static library.

  SUFFIX
       What comes after the library name.

       A target property that can be set to override the suffix (such as
       ".so") on a library name.

  VERSION
       What version number is this target.

       For shared libraries VERSION and SOVERSION can be used to specify the
       build version and api version respectively.  When building or
       installing appropriate symlinks are created if the platform supports
       symlinks and the linker supports so-names.  If only one of both is
       specified the missing is assumed to have the same version number.  For
       executables VERSION can be used to specify the build version.  When
       building or installing appropriate symlinks are created if the
       platform supports symlinks.  For shared libraries and executables on
       Windows the VERSION attribute is parsed to extract a "major.minor"
       version number.  These numbers are used as the image version of the
       binary.

  WIN32_EXECUTABLE
       Build an executable with a WinMain entry point on windows.

       When this property is set to true the executable when linked on
       Windows will be created with a WinMain() entry point instead of of
       just main().This makes it a GUI executable instead of a console
       application.  See the CMAKE_MFC_FLAG variable documentation to
       configure use of MFC for WinMain executables.

  XCODE_ATTRIBUTE_<an-attribute>
       Set Xcode target attributes directly.

       Tell the Xcode generator to set '<an-attribute>' to a given value in
       the generated Xcode project.  Ignored on other generators.

------------------------------------------------------------------------------
Properties on Tests

  FAIL_REGULAR_EXPRESSION
       If the output matches this regular expression the test will fail.

       If set, if the output matches one of specified regular expressions,
       the test will fail.For example: PASS_REGULAR_EXPRESSION
       "[^a-z]Error;ERROR;Failed"

  MEASUREMENT
       Specify a DART measurement and value to be reported for a test.

       If set to a name then that name will be reported to DART as a named
       measurement with a value of 1.  You may also specify a value by
       setting MEASUREMENT to "measurement=value".

  PASS_REGULAR_EXPRESSION
       The output must match this regular expression for the test to pass.

       If set, the test output will be checked against the specified regular
       expressions and at least one of the regular expressions has to match,
       otherwise the test will fail.

  TIMEOUT
       How many seconds to allow for this test.

       This property if set will limit a test to not take more than the
       specified number of seconds to run.  If it exceeds that the test
       process will be killed and ctest will move to the next test.  This
       setting takes precedence over DART_TESTING_TIMEOUT and
       CTEST_TESTING_TIMEOUT.

  WILL_FAIL
       If set to true, this will invert the pass/fail flag of the test.

       This property can be used for tests that are expected to fail and
       return a non zero return code.

------------------------------------------------------------------------------
Properties on Source Files

  ABSTRACT
       Is this source file an abstract class.

       A property on a source file that indicates if the source file
       represents a class that is abstract.  This only makes sense for
       languages that have a notion of an abstract class and it is only used
       by some tools that wrap classes into other languages.

  COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a source file.

       The COMPILE_DEFINITIONS property may be set to a list of preprocessor
       definitions using the syntax VAR or VAR=value.  Function-style
       definitions are not supported.  CMake will automatically escape the
       value correctly for the native build system (note that CMake language
       syntax may require escapes to specify some values).  This property may
       be set on a per-configuration basis using the name
       COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case name (ex.
       "COMPILE_DEFINITIONS_DEBUG").

       CMake will automatically drop some definitions that are not supported
       by the native build tool.  The VS6 IDE does not support definitions
       with values (but NMake does).  Xcode does not support
       per-configuration definitions on source files.

       Dislaimer: Most native build tools have poor support for escaping
       certain values.  CMake has work-arounds for many cases but some values
       may just not be possible to pass correctly.  If a value does not seem
       to be escaped correctly, do not attempt to work-around the problem by
       adding escape sequences to the value.  Your work-around may break in a
       future version of CMake that has improved escape support.  Instead
       consider defining the macro in a (configured) header file.  Then
       report the limitation.

  COMPILE_DEFINITIONS_<CONFIG>
       Per-configuration preprocessor definitions on a source file.

       This is the configuration-specific version of COMPILE_DEFINITIONS.
       Note that Xcode does not support per-configuration source file flags
       so this property will be ignored by the Xcode generator.

  COMPILE_FLAGS
       Additional flags to be added when compiling this source file.

       These flags will be added to the list of compile flags when this
       source file builds.  Use COMPILE_DEFINITIONS to pass additional
       preprocessor definitions.

  EXTERNAL_OBJECT
       If set to true then this is an object file.

       If this property is set to true then the source file is really an
       object file and should not be compiled.  It will still be linked into
       the target though.

  GENERATED
       Is this source file generated as part of the build process.

       If a source file is generated by the build process CMake will handle
       it differently in temrs of dependency checking etc.  Otherwise having
       a non-existent source file could create problems.

  HEADER_FILE_ONLY
       Is this source file only a header file.

       A property on a source file that indicates if the source file is a
       header file with no associated implementation.  This is set
       automatically based on the file extension and is used by CMake to
       determine is certain dependency information should be computed.

  KEEP_EXTENSION
       Make the output file have the same extension as the source file.

       If this property is set then the file extension of the output file
       will be the same as that of the source file.  Normally the output file
       extension is computed based on the language of the source file, for
       example .cxx will go to a .o extension.

  LANGUAGE
       What programming language is the file.

       A property that can be set to indicate what programming language the
       source file is.  If it is not set the language is determined based on
       the file extension.  Typical values are CXX C etc.

  LOCATION
       The full path to a source file.

       A read only property on a SOURCE FILE that contains the full path to
       the source file.

  MACOSX_PACKAGE_LOCATION
       Place a source file inside a Mac OS X bundle or framework.

       Executable targets with the MACOSX_BUNDLE property set are built as
       Mac OS X application bundles on Apple platforms.  Shared library
       targets with the FRAMEWORK property set are built as Mac OS X
       frameworks on Apple platforms.  Source files listed in the target with
       this property set will be copied to a directory inside the bundle or
       framework content folder specified by the property value.  For bundles
       the content folder is "<name>.app/Contents".  For frameworks the
       content folder is "<name>.framework/Versions/<version>".  See the
       PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties for
       specifying files meant for Headers, PrivateHeadres, or Resources
       directories.

  OBJECT_DEPENDS
       Additional dependencies.

       Additional dependencies that should be checked as part of building
       this source file.

  OBJECT_OUTPUTS
       Additional outputs for a Makefile rule.

       Additional outputs created by compilation of this source file.  If any
       of these outputs is missing the object will be recompiled.  This is
       supported only on Makefile generators and will be ignored on other
       generators.

  SYMBOLIC
       Is this just a name for a rule.

       If SYMBOLIC (boolean) is set to true the build system will be informed
       that the source file is not actually created on disk but instead used
       as a symbolic name for a build rule.

  WRAP_EXCLUDE
       Exclude this source file from any code wrapping techniques.

       Some packages can wrap source files into alternate languages to
       provide additional functionality.  For example, C++ code can be
       wrapped into Java or Python etc using SWIG etc.  If WRAP_EXCLUDE is
       set to true (1 etc) that indicates then this source file should not be
       wrapped.

------------------------------------------------------------------------------
Compatibility Commands

  CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.

This is the documentation for now obsolete listfile commands from previous
CMake versions, which are still supported for compatibility reasons.  You
should instead use the newer, faster and shinier new commands.  ;-)

  build_name
       Deprecated.  Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER} instead.

         build_name(variable)

       Sets the specified variable to a string representing the platform and
       compiler settings.  These values are now available through the
       CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.

  exec_program
       Deprecated.  Use the execute_process() command instead.

       Run an executable program during the processing of the CMakeList.txt
       file.

         exec_program(Executable [directory in which to run]
                      [ARGS <arguments to executable>]
                      [OUTPUT_VARIABLE <var>]
                      [RETURN_VALUE <var>])

       The executable is run in the optionally specified directory.  The
       executable can include arguments if it is double quoted, but it is
       better to use the optional ARGS argument to specify arguments to the
       program.  This is because cmake will then be able to escape spaces in
       the executable path.  An optional argument OUTPUT_VARIABLE specifies a
       variable in which to store the output.  To capture the return value of
       the execution, provide a RETURN_VALUE.  If OUTPUT_VARIABLE is
       specified, then no output will go to the stdout/stderr of the console
       running cmake.


  export_library_dependencies
       Deprecated.  Use INSTALL(EXPORT) or EXPORT command.

       This command generates an old-style library dependencies file.
       Projects requiring CMake 2.6 or later should not use the command.  Use
       instead the install(EXPORT) command to help export targets from an
       installation tree and the export() command to export targets from a
       build tree.

       The old-style library dependencies file does not take into account
       per-configuration names of libraries or the LINK_INTERFACE_LIBRARIES
       target property.

         export_library_dependencies(<file> [APPEND])

       Create a file named <file> that can be included into a CMake listfile
       with the INCLUDE command.  The file will contain a number of SET
       commands that will set all the variables needed for library dependency
       information.  This should be the last command in the top level
       CMakeLists.txt file of the project.  If the APPEND option is
       specified, the SET commands will be appended to the given file instead
       of replacing it.

  install_files
       Deprecated.  Use the install(FILES ) command instead.

       This command has been superceded by the install command.  It is
       provided for compatibility with older CMake code.  The FILES form is
       directly replaced by the FILES form of the install command.  The
       regexp form can be expressed more clearly using the GLOB form of the
       file command.

         install_files(<dir> extension file file ...)

       Create rules to install the listed files with the given extension into
       the given directory.  Only files existing in the current source tree
       or its corresponding location in the binary tree may be listed.  If a
       file specified already has an extension, that extension will be
       removed first.  This is useful for providing lists of source files
       such as foo.cxx when you want the corresponding foo.h to be installed.
       A typical extension is '.h'.

         install_files(<dir> regexp)

       Any files in the current source directory that match the regular
       expression will be installed.

         install_files(<dir> FILES file file ...)

       Any files listed after the FILES keyword will be installed explicitly
       from the names given.  Full paths are allowed in this form.

       The directory <dir> is relative to the installation prefix, which is
       stored in the variable CMAKE_INSTALL_PREFIX.

  install_programs
       Deprecated.  Use the install(PROGRAMS ) command instead.

       This command has been superceded by the install command.  It is
       provided for compatibility with older CMake code.  The FILES form is
       directly replaced by the PROGRAMS form of the INSTALL command.  The
       regexp form can be expressed more clearly using the GLOB form of the
       FILE command.

         install_programs(<dir> file1 file2 [file3 ...])
         install_programs(<dir> FILES file1 [file2 ...])

       Create rules to install the listed programs into the given directory.
       Use the FILES argument to guarantee that the file list version of the
       command will be used even when there is only one argument.

         install_programs(<dir> regexp)

       In the second form any program in the current source directory that
       matches the regular expression will be installed.

       This command is intended to install programs that are not built by
       cmake, such as shell scripts.  See the TARGETS form of the INSTALL
       command to create installation rules for targets built by cmake.

       The directory <dir> is relative to the installation prefix, which is
       stored in the variable CMAKE_INSTALL_PREFIX.

  install_targets
       Deprecated.  Use the install(TARGETS ) command instead.

       This command has been superceded by the install command.  It is
       provided for compatibility with older CMake code.

         install_targets(<dir> [RUNTIME_DIRECTORY dir] target target)

       Create rules to install the listed targets into the given directory.
       The directory <dir> is relative to the installation prefix, which is
       stored in the variable CMAKE_INSTALL_PREFIX.  If RUNTIME_DIRECTORY is
       specified, then on systems with special runtime files (Windows DLL),
       the files will be copied to that directory.

  link_libraries
       Deprecated.  Use the target_link_libraries() command instead.

       Link libraries to all targets added later.

         link_libraries(library1 <debug | optimized> library2 ...)

       Specify a list of libraries to be linked into any following targets
       (typically added with the add_executable or add_library calls).  This
       command is passed down to all subdirectories.  The debug and optimized
       strings may be used to indicate that the next library listed is to be
       used only for that specific type of build.

  make_directory
       Deprecated.  Use the file(MAKE_DIRECTORY ) command instead.

         make_directory(directory)

       Creates the specified directory.  Full paths should be given.  Any
       parent directories that do not exist will also be created.  Use with
       care.

  remove
       Deprecated.  Use the list(REMOVE_ITEM ) command instead.

         remove(VAR VALUE VALUE ...)

       Removes VALUE from the variable VAR.  This is typically used to remove
       entries from a vector (e.g.  semicolon separated list).  VALUE is
       expanded.

  subdir_depends
       Deprecated.  Does nothing.

         subdir_depends(subdir dep1 dep2 ...)

       Does not do anything.  This command used to help projects order
       parallel builds correctly.  This functionality is now automatic.

  subdirs
       Deprecated.  Use the add_subdirectory() command instead.

       Add a list of subdirectories to the build.

         subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...] [PREORDER] )

       Add a list of subdirectories to the build.  The add_subdirectory
       command should be used instead of subdirs although subdirs will still
       work.  This will cause any CMakeLists.txt files in the sub directories
       to be processed by CMake.  Any directories after the PREORDER flag are
       traversed first by makefile builds, the PREORDER flag has no effect on
       IDE projects.  Any directories after the EXCLUDE_FROM_ALL marker will
       not be included in the top level makefile or project file.  This is
       useful for having CMake create makefiles or projects for a set of
       examples in a project.  You would want CMake to generate makefiles or
       project files for all the examples at the same time, but you would not
       want them to show up in the top level project or be built each time
       make is run from the top.

  use_mangled_mesa
       Copy mesa headers for use in combination with system GL.

         use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)

       The path to mesa includes, should contain gl_mangle.h.  The mesa
       headers are copied to the specified output directory.  This allows
       mangled mesa headers to override other GL headers by being added to
       the include directory path earlier.

  utility_source
       Specify the source tree of a third-party utility.

         utility_source(cache_entry executable_name
                        path_to_source [file1 file2 ...])

       When a third-party utility's source is included in the distribution,
       this command specifies its location and name.  The cache entry will
       not be set unless the path_to_source and all listed files exist.  It
       is assumed that the source tree of the utility will have been built
       before it is needed.

       When cross compiling CMake will print a warning if a utility_source()
       command is executed, because in many cases it is used to build an
       executable which is executed later on.  This doesn't work when cross
       compiling, since the executable can run only on their target platform.
       So in this case the cache entry has to be adjusted manually so it
       points to an executable which is runnable on the build host.

  variable_requires
       Deprecated.  Use the if() command instead.

       Assert satisfaction of an option's required variables.

         variable_requires(TEST_VARIABLE RESULT_VARIABLE
                           REQUIRED_VARIABLE1
                           REQUIRED_VARIABLE2 ...)

       The first argument (TEST_VARIABLE) is the name of the variable to be
       tested, if that variable is false nothing else is done.  If
       TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a
       variable that is set to true if all the required variables are set.
       The rest of the arguments are variables that must be true or not set
       to NOTFOUND to avoid an error.  If any are not true, an error is
       reported.

  write_file
       Deprecated.  Use the file(WRITE ) command instead.

         write_file(filename "message to write"... [APPEND])

       The first argument is the file name, the rest of the arguments are
       messages to write.  If the argument APPEND is specified, then the
       message will be appended.

       NOTE 1: file(WRITE ...  and file(APPEND ...  do exactly the same as
       this one but add some more functionality.

       NOTE 2: When using write_file the produced file cannot be used as an
       input to CMake (CONFIGURE_FILE, source file ...) because it will lead
       to an infinite loop.  Use configure_file if you want to generate input
       files to CMake.

Standard CMake Modules

The following modules are provided with CMake.  They can be used with
INCLUDE(ModuleName).

  CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

This is the documentation for the modules and scripts coming with CMake.
Using these modules you can check the computer system for installed software
packages, features of the compiler and the existance of headers to name just
a few.

  AddFileDependencies
       ADD_FILE_DEPENDENCIES(source_file depend_files...)

       Adds the given files as dependencies to source_file


  BundleUtilities
        

       BundleUtilities.cmake

       A collection of CMake utility functions useful for dealing with .app
       bundles on the Mac and bundle-like directories on any OS.

       The following functions are provided by this script:

          get_bundle_main_executable
          get_dotapp_dir
          get_bundle_and_executable
          get_bundle_all_executables
          get_item_key
          clear_bundle_keys
          set_bundle_key_values
          get_bundle_keys
          copy_resolved_item_into_bundle
          fixup_bundle_item
          fixup_bundle
          copy_and_fixup_bundle
          verify_bundle_prerequisites
          verify_bundle_symlinks
          verify_app

       

       Requires CMake 2.6 or greater because it uses function, break and
       PARENT_SCOPE.  Also depends on GetPrerequisites.cmake.

  CMakeBackwardCompatibilityCXX
       define a bunch of backwards compatibility variables

         CMAKE_ANSI_CXXFLAGS - flag for ansi c++ 
         CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
         INCLUDE(TestForANSIStreamHeaders)
         INCLUDE(CheckIncludeFileCXX)
         INCLUDE(TestForSTDNamespace)
         INCLUDE(TestForANSIForScope)


  CMakeDependentOption
       Macro to provide an option dependent on other options.

       This macro presents an option to the user only if a set of other
       conditions are true.  When the option is not presented a default value
       is used, but any value set by the user is preserved for when the
       option is presented again.  Example invocation:

         CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
                                "USE_BAR;NOT USE_ZOT" OFF)

       If USE_BAR is true and USE_ZOT is false, this provides an option
       called USE_FOO that defaults to ON.  Otherwise, it sets USE_FOO to
       OFF.  If the status of USE_BAR or USE_ZOT ever changes, any value for
       the USE_FOO option is saved so that when the option is re-enabled it
       retains its old value.

  CMakeDetermineASM-ATTCompiler
        

       determine the compiler to use for ASM using AT&T syntax

  CMakeDetermineASMCompiler
        

       determine the compiler to use for ASM programs

  CMakeExportBuildSettings
       export build settings from a project.

         CMAKE_EXPORT_BUILD_SETTINGS(SETTINGS_FILE)

       macro defined to export the build settings for use by another project.

         SETTINGS_FILE - the file into which the settings are to be stored.


  CMakeFindFrameworks
       helper module to find OSX frameworks

  CMakeForceCompiler
        

       This module defines macros intended for use by cross-compiling
       toolchain files when CMake is not able to automatically detect the
       compiler identification.

       Macro CMAKE_FORCE_C_COMPILER has the following signature:

          CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_C_COMPILER to the given compiler and the cmake internal
       variable CMAKE_C_COMPILER_ID to the given compiler-id.  It also
       bypasses the check for working compiler and basic compiler information
       tests.

       Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

          CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_CXX_COMPILER to the given compiler and the cmake
       internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id.  It
       also bypasses the check for working compiler and basic compiler
       information tests.

       So a simple toolchain file could look like this:

          INCLUDE (CMakeForceCompiler)
          SET(CMAKE_SYSTEM_NAME Generic)
          CMAKE_FORCE_C_COMPILER   (chc12 MetrowerksHicross)
          CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)


  CMakeImportBuildSettings
       import build settings from another project

         CMAKE_IMPORT_BUILD_SETTINGS(SETTINGS_FILE) 

       macro defined to import the build settings from another project.
       SETTINGS_FILE is a file created by the other project's call to the
       CMAKE_EXPORT_BUILD_SETTINGS macro, see CMakeExportBuildSettings.

  CMakeJavaInformation
        

       This should be included before the _INIT variables are used to
       initialize the cache.  Since the rule variables have if blocks on
       them, users can still define them here.  But, it should still be after
       the platform file so changes can be made to those values.

  CMakePrintSystemInformation
       print system information

       This file can be used for diagnostic purposes just include it in a
       project to see various internal CMake variables.

  CPack
       Build binary and source package installers

       

       The CPack module generates binary and source installers in a variety
       of formats using the cpack program.  Inclusion of the CPack module
       adds two new targets to the resulting makefiles, package and
       package_source, which build the binary and source installers,
       respectively.  The generated binary installers contain everything
       installed via CMake's INSTALL command (and the deprecated
       INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).

       For certain kinds of binary installers (including the graphical
       installers on Mac OS X and Windows), CPack generates installers that
       allow users to select individual application components to install.
       The contents of each of the components are identified by the COMPONENT
       argument of CMake's INSTALL command.  These components can be
       annotated with user-friendly names and descriptions, inter-component
       dependencies, etc., and grouped in various ways to customize the
       resulting installer.  See the cpack_add_* commands, described below,
       for more information about component-specific installations.

       Before including the CPack module, there are a variety of variables
       that can be set to customize the resulting installers.  The most
       commonly-used variables are:

          CPACK_PACKAGE_NAME - The name of the package (or application). If
          not specified, defaults to the project name.

       

          CPACK_PACKAGE_VENDOR - The name of the package vendor (e.g.,
          "Kitware").

       

          CPACK_PACKAGE_VERSION_MAJOR - Package major Version

       

          CPACK_PACKAGE_VERSION_MINOR - Package minor Version

       

          CPACK_PACKAGE_VERSION_PATCH - Package patch Version

       

          CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
          project. Used, for example, the introduction screen of a
          CPack-generated Windows installer to describe the project.

       

          CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
          project (only a few words).

       

          CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
          not including the extension. For example, cmake-2.6.1-Linux-i686.

       

          CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
          target system, e.g., "CMake 2.5".

       

          CPACK_RESOURCE_FILE_LICENSE - License file for the project, which
          will typically be displayed to the user (often with an explicit
          "Accept" button, for graphical installers) prior to installation.

       

          CPACK_RESOURCE_FILE_README - ReadMe file for the project, which
          typically describes in some detail

       

          CPACK_RESOURCE_FILE_WELCOME - Welcome file for the project, which
          welcomes users to this installer. Typically used in the graphical
          installers on Windows and Mac OS X.

       

          CPACK_MONOLITHIC_INSTALL - Disables the component-based 
          installation mechanism, so that all components are always installed.

       

          CPACK_GENERATOR - List of CPack generators to use. If not
          specified, CPack will create a set of options (e.g.,
          CPACK_BINARY_NSIS) allowing the user to enable/disable individual
          generators.

       

          CPACK_OUTPUT_CONFIG_FILE - The name of the CPack configuration file
          for binary installers that will be generated by the CPack
          module. Defaults to CPackConfig.cmake.

       

          CPACK_PACKAGE_EXECUTABLES - Lists each of the executables along
          with a text label, to be used to create Start Menu shortcuts on
          Windows. For example, setting this to the list ccmake;CMake will
          create a shortcut named "CMake" that will execute the installed
          executable ccmake.

       

          CPACK_STRIP_FILES - List of files to be stripped. Starting with
          CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
          enables stripping of all files (a list of files evaluates to TRUE
          in CMake, so this change is compatible).

       

       The following CPack variables are specific to source packages, and
       will not affect binary packages:

          CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package,
          e.g., cmake-2.6.1

       

          CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
          will be stripped. Starting with CMake 2.6.0
          CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
          stripping of all files (a list of files evaluates to TRUE in CMake,
          so this change is compatible).

       

          CPACK_SOURCE_GENERATOR - List of generators used for the source
          packages. As with CPACK_GENERATOR, if this is not specified then
          CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
          allowing users to select which packages will be generated.

       

          CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack
          configuration file for source installers that will be generated by
          the CPack module. Defaults to CPackSourceConfig.cmake.

       

          CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
          that won't be packaged when building a source package. This is a
          list of patterns, e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*

       

       The following variables are specific to the graphical installers built
       on Windows using the Nullsoft Installation System.

          CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
          installing this project.

       

          CPACK_NSIS_MUI_ICON - The icon file (.ico) for the generated
          install program.

       

          CPACK_NSIS_MUI_UNIICON - The icon file (.ico) for the generated
          uninstall program.

       

          CPACK_PACKAGE_ICON - A branding image that will be displayed inside
          the installer.

       

          CPACK_NSIS_EXTRA_INSTALL_COMMANDS - Extra NSIS commands that will
          be added to the install Section.

       

          CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS - Extra NSIS commands that will
          be added to the uninstall Section.

       

          CPACK_NSIS_COMPRESSOR - The arguments that will be passed to the
          NSIS SetCompressor command.

       

          CPACK_NSIS_MODIFY_PATH - If this is set to "ON", then an extra page
          will appear in the installer that will allow the user to choose
          whether the program directory should be added to the system PATH
          variable.

       

          CPACK_NSIS_DISPLAY_NAME - The title displayed at the top of the
          installer.

       

          CPACK_NSIS_INSTALLED_ICON_NAME - A path to the executable that
          contains the installer icon.

       

          CPACK_NSIS_HELP_LINK - URL to a web site providing assistance in
          installing your application.

       

          CPACK_NSIS_URL_INFO_ABOUT - URL to a web site providing more
          information about your application.

       

          CPACK_NSIS_CONTACT - Contact information for questions and comments
          about the installation process.

       

          CPACK_NSIS_CREATE_ICONS_EXTRA - Additional NSIS commands for
          creating start menu shortcuts.

       

          CPACK_NSIS_DELETE_ICONS_EXTRA -Additional NSIS commands to
          uninstall start menu shortcuts.

       

       The following variable is specific to installers build on Mac OS X
       using PackageMaker:

          CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
          resulting PackageMaker archive should be compatible
          with. Different versions of Mac OS X support different
          features. For example, CPack can only build component-based
          installers for Mac OS X 10.4 or newer, and can only build
          installers that download component son-the-fly for Mac OS X 10.5
          or newer. If left blank, this value will be set to the minimum
          version of Mac OS X that supports the requested features. Set this
          variable to some value (e.g., 10.4) only if you want to guarantee
          that your installer will work on that version of Mac OS X, and
          don't mind missing extra features available in the installer
          shipping with later versions of Mac OS X.

       

       The following variables are for advanced uses of CPack:

          CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
          project is CMake project. Defaults to the value of CMAKE_GENERATOR;
          few users will want to change this setting.

       

          CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
          what project to install. The four values are: Build directory,
          Project Name, Project Component, Directory. If omitted, CPack will
          build an installer that installers everything.

       

          CPACK_SYSTEM_NAME - System name, defaults to the value of
          ${CMAKE_SYSTEM_NAME}.

       

          CPACK_PACKAGE_VERSION - Package full version, used internally. By
          default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
          CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

       

          CPACK_TOPLEVEL_TAG - Directory for the installed files.

       

          CPACK_INSTALL_COMMANDS - Extra commands to install components.

       

          CPACK_INSTALL_DIRECTORIES - Extra directories to install.

       

       Component-specific installation allows users to select specific sets
       of components to install during the install process.  Installation
       components are identified by the COMPONENT argument of CMake's INSTALL
       commands, and should be further described by the following CPack
       commands:

          cpack_add_component - Describes a CPack installation component
          named by the COMPONENT argument to a CMake INSTALL command.

       

            cpack_add_component(compname
                                [DISPLAY_NAME name]
                                [DESCRIPTION description]
                                [HIDDEN | REQUIRED | DISABLED ]
                                [GROUP group]
                                [DEPENDS comp1 comp2 ... ]
                                [INSTALL_TYPES type1 type2 ... ]
                                [DOWNLOADED]
                                [ARCHIVE_FILE filename])

       

          The cmake_add_component command describes an installation
          component, which the user can opt to install or remove as part of
          the graphical installation process. compname is the name of the
          component, as provided to the COMPONENT argument of one or more
          CMake INSTALL commands.

       

          DISPLAY_NAME is the displayed name of the component, used in
          graphical installers to display the component name. This value can
          be any string.

       

          DESCRIPTION is an extended description of the component, used in
          graphical installers to give the user additional information about
          the component. Descriptions can span multiple lines using "\n" as
          the line separator. Typically, these descriptions should be no
          more than a few lines long.

       

          HIDDEN indicates that this component will be hidden in the
          graphical installer, so that the user cannot directly change
          whether it is installed or not.

       

          REQUIRED indicates that this component is required, and therefore
          will always be installed. It will be visible in the graphical
          installer, but it cannot be unselected. (Typically, required
          components are shown greyed out).

       

          DISABLED indicates that this component should be disabled
          (unselected) by default. The user is free to select this component
          for installation, unless it is also HIDDEN.

       

          DEPENDS lists the components on which this component depends. If
          this component is selected, then each of the components listed
          must also be selected. The dependency information is encoded
          within the installer itself, so that users cannot install
          inconsitent sets of components.

       

          GROUP names the component group of which this component is a
          part. If not provided, the component will be a standalone
          component, not part of any component group. Component groups are
          described with the cpack_add_component_group command, detailed
          below.

       

          INSTALL_TYPES lists the installation types of which this component
          is a part. When one of these installations types is selected, this
          component will automatically be selected. Installation types are
          described with the cpack_add_install_type command, detailed below.

       

          DOWNLOADED indicates that this component should be downloaded
          on-the-fly by the installer, rather than packaged in with the
          installer itself. For more information, see the cpack_configure_downloads
          command.

       

          ARCHIVE_FILE provides a name for the archive file created by CPack
          to be used for downloaded components. If not supplied, CPack will
          create a file with some name based on CPACK_PACKAGE_FILE_NAME and
          the name of the component. See cpack_configure_downloads for more
          information.

       

          cpack_add_component_group - Describes a group of related CPack
          installation components.

       

            cpack_add_component_group(groupname
                                     [DISPLAY_NAME name]
                                     [DESCRIPTION description]
                                     [PARENT_GROUP parent]
                                     [EXPANDED]
                                     [BOLD_TITLE])

       

          The cpack_add_component_group describes a group of installation
          components, which will be placed together within the listing of
          options. Typically, component groups allow the user to
          select/deselect all of the components within a single group via a
          single group-level option. Use component groups to reduce the
          complexity of installers with many options. groupname is an
          arbitrary name used to identify the group in the GROUP argument of
          the cpack_add_component command, which is used to place a
          component in a group. The name of the group must not conflict with
          the name of any component.

       

          DISPLAY_NAME is the displayed name of the component group, used in
          graphical installers to display the component group name. This
          value can be any string.

       

          DESCRIPTION is an extended description of the component group,
          used in graphical installers to give the user additional
          information about the components within that group. Descriptions
          can span multiple lines using "\n" as the line
          separator. Typically, these descriptions should be no more than a
          few lines long.

       

          PARENT_GROUP, if supplied, names the parent group of this group. 
          Parent groups are used to establish a hierarchy of groups, 
          providing an arbitrary hierarchy of groups.

       

          EXPANDED indicates that, by default, the group should show up as
          "expanded", so that the user immediately sees all of the
          components within the group. Otherwise, the group will initially
          show up as a single entry.

       

          BOLD_TITLE indicates that the group title should appear in bold,
          to call the user's attention to the group.

       

          cpack_add_install_type - Add a new installation type containing a
          set of predefined component selections to the graphical installer.
                             
            cpack_add_install_type(typename
                                   [DISPLAY_NAME name])   

       

          The cpack_add_install_type command identifies a set of preselected
          components that represents a common use case for an
          application. For example, a "Developer" install type might include
          an application along with its header and library files, while an
          "End user" install type might just include the application's
          executable. Each component identifies itself with one or more
          install types via the INSTALL_TYPES argument to
          cpack_add_component.

       

          DISPLAY_NAME is the displayed name of the install type, which will
          typically show up in a drop-down box within a graphical
          installer. This value can be any string.

       

          cpack_configure_downloads - Configure CPack to download selected
          components on-the-fly as part of the installation process.

       

            cpack_configure_downloads(site
                                      [UPLOAD_DIRECTORY dirname]
                                      [ALL]
                                      [ADD_REMOVE|NO_ADD_REMOVE])

       

          The cpack_configure_downloads command configures installation-time
          downloads of selected components. For each downloadable component,
          CPack will create an archive containing the contents of that
          component, which should be uploaded to the given site. When the
          user selects that component for installation, the installer will
          download and extract the component in place. This feature is
          useful for creating small installers that only download the
          requested components, saving bandwidth. Additionally, the
          installers are small enough that they will be installed as part of
          the normal installation process, and the "Change" button in
          Windows Add/Remove Programs control panel will allow one to add or
          remove parts of the application after the original
          installation. On Windows, the downloaded-components functionality
          requires the ZipDLL plug-in for NSIS, available at:

       

            http://nsis.sourceforge.net/ZipDLL_plug-in

       

          On Mac OS X, installers that download components on-the-fly can
          only be built and installed on system using Mac OS X 10.5 or
          later.

       

          The site argument is a URL where the archives for downloadable 
          components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
          All of the archives produced by CPack should be uploaded to that location.

       

          UPLOAD_DIRECTORY is the local directory where CPack will create the 
          various archives for each of the components. The contents of this
          directory should be uploaded to a location accessible by the URL given
          in the site argument. If omitted, CPack will use the directory CPackUploads
          inside the CMake binary directory to store the generated archives.

       

          The ALL flag indicates that all components be downloaded. Otherwise, only 
          those components explicitly marked as DOWNLOADED or that have a specified 
          ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
          ADD_REMOVE (unless NO_ADD_REMOVE is specified).

       

          ADD_REMOVE indicates that CPack should install a copy of the installer
          that can be called from Windows' Add/Remove Programs dialog (via the 
          "Modify" button) to change the set of installed components. NO_ADD_REMOVE
          turns off this behavior. This option is ignored on Mac OS X.

  Dart
       Configure a project for testing with CTest or old Dart Tcl Client

       This file is the backwards-compatibility version of the CTest module.
       It supports using the old Dart 1 Tcl client for driving dashboard
       submissions as well as testing with CTest.  This module should be
       included in the CMakeLists.txt file at the top of a project.  Typical
       usage:

         INCLUDE(Dart)
         IF(BUILD_TESTING)
           # ... testing related CMake code ...
         ENDIF(BUILD_TESTING)

       The BUILD_TESTING option is created by the Dart module to determine
       whether testing support should be enabled.  The default is ON.

  Documentation
       DocumentationVTK.cmake

       This file provides support for the VTK documentation framework.  It
       relies on several tools (Doxygen, Perl, etc).

  FeatureSummary
       Macros for generating a summary of enabled/disabled features

       

       PRINT_ENABLED_FEATURES()

          Print a summary of all enabled features. By default all successfull
          FIND_PACKAGE() calls will appear here, except the ones which used the QUIET keyword.
          Additional features can be added by appending an entry to the global ENABLED_FEATURES
          property. If SET_FEATURE_INFO() is used for that feature, the output will be much 
          more informative.

       

       PRINT_DISABLED_FEATURES()

          Same as PRINT_ENABLED_FEATURES(), but for disabled features. It can be extended
          the same way by adding to the global property DISABLED_FEATURES.

       

       SET_FEATURE_INFO(NAME DESCRIPTION [URL [COMMENT] ] )

           Use this macro to set up information about the named feature, which will
           then be displayed by PRINT_ENABLED/DISABLED_FEATURES().
           Example: SET_FEATURE_INFO(LibXml2 "XML processing library." "http://xmlsoft.org/")

       


  FindASPELL
       Try to find ASPELL

       Once done this will define

         ASPELL_FOUND - system has ASPELL
         ASPELL_INCLUDE_DIR - the ASPELL include directory
         ASPELL_LIBRARIES - The libraries needed to use ASPELL
         ASPELL_DEFINITIONS - Compiler switches required for using ASPELL


  FindAVIFile
       Locate AVIFILE library and include paths

       AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for
       i386 machines to use various AVI codecs.  Support is limited beyond
       Linux.  Windows provides native AVI support, and so doesn't need this
       library.  This module defines

         AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
         AVIFILE_LIBRARIES, the libraries to link against
         AVIFILE_DEFINITIONS, definitions to use when compiling
         AVIFILE_FOUND, If false, don't try to use AVIFILE


  FindBLAS
       Find BLAS library

       This module finds an installed fortran library that implements the
       BLAS linear-algebra interface (see http://www.netlib.org/blas/).  The
       list of libraries searched for is taken from the autoconf macro file,
       acx_blas.m4 (distributed at
       http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

       This module sets the following variables:

         BLAS_FOUND - set to true if a library implementing the BLAS interface
           is found
         BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
           and -L).
         BLAS_LIBRARIES - uncached list of libraries (using full path name) to
           link against to use BLAS
         BLAS95_LIBRARIES - uncached list of libraries (using full path name)
           to link against to use BLAS95 interface
         BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
           is found
         BLA_STATIC  if set on this determines what kind of linkage we do (static)
         BLA_VENDOR  if set checks only the specified vendor, if not set checks
            all the posibilities
         BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK

       ######### ## List of vendors (BLA_VENDOR) valid in this module #
       ATLAS, PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32
       (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread
       model, lp64 model), # Intel( older versions of mkl 32 and 64 bit),
       ACML,Apple, NAS, Generic C/CXX should be enabled to use Intel mkl

  FindBZip2
       Try to find BZip2

       Once done this will define

         BZIP2_FOUND - system has BZip2
         BZIP2_INCLUDE_DIR - the BZip2 include directory
         BZIP2_LIBRARIES - Link these to use BZip2
         BZIP2_DEFINITIONS - Compiler switches required for using BZip2
         BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_


  FindBoost
       Try to find Boost include dirs and libraries

       Usage of this module as follows:

            SET(Boost_USE_STATIC_LIBS ON)
            SET(Boost_USE_MULTITHREAD OFF)
            FIND_PACKAGE( Boost 1.34.1 COMPONENTS date_time filesystem iostreams ... )

       

       The Boost_ADDITIONAL_VERSIONS variable can be used to specify a list
       of boost version numbers that should be taken into account when
       searching for the libraries.  Unfortunately boost puts the version
       number into the actual filename for the libraries, so this might be
       needed in the future when new Boost versions are released.

       Currently this module searches for the following version numbers:
       1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1,
       1.36, 1.36.0, 1.36.1

       The components list needs to be the actual names of boost libraries,
       that is the part of the actual library files that differ on different
       libraries.  So its "date_time" for "libboost_date_time...".  Anything
       else will result in errors

       You can provide a minimum version number that should be used.  If you
       provide this version number and specify the REQUIRED attribute, this
       module will fail if it can't find the specified or a later version.
       If you specify a version number this is automatically put into the
       considered list of version numbers and thus doesn't need to be
       specified in the Boost_ADDITIONAL_VERSIONS variable

       Variables used by this module, they can change the default behaviour
       and need to be set before calling find_package:

         Boost_USE_MULTITHREAD         Can be set to OFF to use the non-multithreaded
                                       boost libraries. Defaults to ON.
         Boost_USE_STATIC_LIBS         Can be set to ON to force the use of the static

       Created by Eric Wing.  I'm not a gdal user, but OpenSceneGraph uses it
       for osgTerrain so I whipped this module together for completeness.  I
       actually don't know the conventions or where files are typically
       placed in distros.  Any real gdal users are encouraged to correct this
       (but please don't break the OS X framework stuff when doing so which
       is what usually seems to happen).

       It also adds the following macros (from KDE3Macros.cmake) SRCS_VAR is
       always the variable which contains the list of source files for your
       application or library.

       KDE3_AUTOMOC(file1 ...  fileN)

           Call this if you want to have automatic moc file handling.
           This means if you include "foo.moc" in the source file foo.cpp
           a moc file for the header foo.h will be created automatically.
           You can set the property SKIP_AUTOMAKE using SET_SOURCE_FILES_PROPERTIES()
           to exclude some files in the list from being processed.

       

       KDE3_ADD_MOC_FILES(SRCS_VAR file1 ...  fileN )

           If you don't use the KDE3_AUTOMOC() macro, for the files
           listed here moc files will be created (named "foo.moc.cpp")

       

       KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ...  headerN.h )

           Use this to generate DCOP skeletions from the listed headers.

       

       KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ...  headerN.h )

            Use this to generate DCOP stubs from the listed headers.

       

       KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ...  fileN.ui )

           Use this to add the Qt designer ui files to your application/library.

       

       KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ...  fileN.kcfgc )

           Use this to add KDE kconfig compiler files to your application/library.

       

       KDE3_INSTALL_LIBTOOL_FILE(target)

           This will create and install a simple libtool file for the given target.

       

       KDE3_ADD_EXECUTABLE(name file1 ...  fileN )

           Currently identical to ADD_EXECUTABLE(), may provide some advanced features in the future.

       

       KDE3_ADD_KPART(name [WITH_PREFIX] file1 ...  fileN )

           Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
           If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
           It creates and installs an appropriate libtool la-file.

       

       KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ...  fileN )

           Create a KDE application in the form of a module loadable via kdeinit.
           A library named kdeinit_<name> will be created and a small executable which links to it.

       

       The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no
       longer supported.

  FindLAPACK
       Find LAPACK library

       This module finds an installed fortran library that implements the
       LAPACK linear-algebra interface (see http://www.netlib.org/lapack/).

       The approach follows that taken for the autoconf macro file,
       acx_lapack.m4 (distributed at
       http://ac-archive.sourceforge.net/ac-archive/acx_lapack.html).

       This module sets the following variables:

         LAPACK_FOUND - set to true if a library implementing the LAPACK interface
           is found
         LAPACK_LINKER_FLAGS - uncached list of required linker flags (excluding -l
           and -L).
         LAPACK_LIBRARIES - uncached list of libraries (using full path name) to
           link against to use LAPACK
         LAPACK95_LIBRARIES - uncached list of libraries (using full path name) to
           link against to use LAPACK95
         LAPACK95_FOUND - set to true if a library implementing the LAPACK f95
           interface is found
         BLA_STATIC  if set on this determines what kind of linkage we do (static)
         BLA_VENDOR  if set checks only the specified vendor, if not set checks
            all the posibilities
         BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK

       ## List of vendors (BLA_VENDOR) valid in this module # Intel(mkl),
       ACML,Apple, NAS, Generic

  FindMPI
       Message Passing Interface (MPI) module.

       

       The Message Passing Interface (MPI) is a library used to write
       high-performance parallel applications that use message passing, and
       is typically deployed on a cluster.  MPI is a standard interface
       (defined by the MPI forum) for which many implementations are
       available.  All of these implementations have somewhat different
       compilation approaches (different include paths, libraries to link
       against, etc.), and this module tries to smooth out those differences.

       This module will set the following variables:

          MPI_FOUND                  TRUE if we have found MPI
          MPI_COMPILE_FLAGS          Compilation flags for MPI programs
          MPI_INCLUDE_PATH           Include path(s) for MPI header
          MPI_LINK_FLAGS             Linking flags for MPI programs
          MPI_LIBRARY                First MPI library to link against (cached)
          MPI_EXTRA_LIBRARY          Extra MPI libraries to link against (cached)
          MPI_LIBRARIES              All libraries to link MPI programs against
          MPIEXEC                    Executable for running MPI programs
          MPIEXEC_NUMPROC_FLAG       Flag to pass to MPIEXEC before giving it the
                                     number of processors to run on
          MPIEXEC_PREFLAGS           Flags to pass to MPIEXEC directly before the
                                     executable to run.
          MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after all other flags.

       

       This module will attempt to auto-detect these settings, first by
       looking for a MPI compiler, which many MPI implementations provide as
       a pass-through to the native compiler to simplify the compilation of
       MPI programs.  The MPI compiler is stored in the cache variable
       MPI_COMPILER, and will attempt to look for commonly-named drivers
       mpic++, mpicxx, mpiCC, or mpicc.  If the compiler driver is found and
       recognized, it will be used to set all of the module variables.  To
       skip this auto-detection, set MPI_LIBRARY and MPI_INCLUDE_PATH in the
       CMake cache.

       If no compiler driver is found or the compiler driver is not
       recognized, this module will then search for common include paths and
       library names to try to detect MPI.

       If CMake initially finds a different MPI than was intended, and you
       want to use the MPI compiler auto-detection for a different MPI
       implementation, set MPI_COMPILER to the MPI compiler driver you want
       to use (e.g., mpicxx) and then set MPI_LIBRARY to the string
       MPI_LIBRARY-NOTFOUND.  When you re-configure, auto-detection of MPI
       will run again with the newly-specified MPI_COMPILER.

       When using MPIEXEC to execute MPI applications, you should typically
       use all of the MPIEXEC flags as follows:

          ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
            ${MPIEXEC_POSTFLAGS} ARGS

       where PROCS is the number of processors on which to execute the
       program, EXECUTABLE is the MPI program, and ARGS are the arguments to
       pass to the MPI program.

  FindMatlab
       this module looks for Matlab

         MOTIF_INCLUDE_DIR  - incude paths to use Motif
         MOTIF_LIBRARIES    - Link these to use Motif


  FindOpenAL
        

       Locate OpenAL This module defines OPENAL_LIBRARY OPENAL_FOUND, if
       false, do not try to link to OpenAL OPENAL_INCLUDE_DIR, where to find
       the headers

       $OPENALDIR is an environment variable that would correspond to the
       ./configure --prefix=$OPENALDIR used in building OpenAL.

       Created by Eric Wing.  This was influenced by the FindSDL.cmake
       module.

  FindOpenGL
       Try to find OpenGL

       Once done this will define

         
         OPENGL_FOUND        - system has OpenGL
         OPENGL_XMESA_FOUND  - system has XMESA
         OPENGL_GLU_FOUND    - system has GLU
         OPENGL_INCLUDE_DIR  - the GL include directory
         OPENGL_LIBRARIES    - Link these to use OpenGL and GLU
          

       If you want to use just GL you can use these values

         OPENGL_gl_LIBRARY   - Path to OpenGL Library
         OPENGL_glu_LIBRARY  - Path to GLU Library
         

       On OSX default to using the framework version of opengl People will
       have to change the cache values of OPENGL_glu_LIBRARY and
       OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

  FindOpenSSL
       Try to find the OpenSSL encryption library

       Once done this will define

         OPENSSL_FOUND - system has the OpenSSL library
         OPENSSL_INCLUDE_DIR - the OpenSSL include directory
         OPENSSL_LIBRARIES - The libraries needed to use OpenSSL


  FindOpenThreads
        

       OpenThreads is a C++ based threading library.  Its largest userbase
       seems to OpenSceneGraph so you might notice I accept OSGDIR as an
       environment path.  I consider this part of the Findosg* suite used to
       find OpenSceneGraph components.  Each component is separate and you
       must opt in to each module.

       Locate OpenThreads This module defines OPENTHREADS_LIBRARY
       OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
       OPENTHREADS_INCLUDE_DIR, where to find the headers

       $OPENTHREADS_DIR is an environment variable that would correspond to
       the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

  FindPHP4
       Find PHP4

       This module finds if PHP4 is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PHP4_INCLUDE_PATH       = path to where php.h can be found
         PHP4_EXECUTABLE         = full path to the php4 binary

       


  FindPNG
       Find the native PNG includes and library

       

       This module defines

         PNG_INCLUDE_DIR, where to find png.h, etc.
         PNG_LIBRARIES, the libraries to link against to use PNG.
         PNG_DEFINITIONS - You should ADD_DEFINITONS(${PNG_DEFINITIONS}) before compiling code that includes png library files.
         PNG_FOUND, If false, do not try to use PNG.

       also defined, but not for general use are

         PNG_LIBRARY, where to find the PNG library.

       None of the above will be defined unles zlib can be found.  PNG
       depends on Zlib

  FindPackageHandleStandardArgs
        

       FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure
       message") VAR1 ...  )

           This macro is intended to be used in FindXXX.cmake modules files.
           It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
           it also sets the <UPPERCASED_NAME>_FOUND variable.
           The package is found if all variables listed are TRUE.
           Example:

       

           FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)

       

           LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and 
           LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
           If it is not found and REQUIRED was used, it fails with FATAL_ERROR, 
           independent whether QUIET was used or not.
           If it is found, the location is reported using the VAR1 argument, so 
           here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
           If the second argument is DEFAULT_MSG, the message in the failure case will 
           be "Could NOT find LibXml2", if you don't like this message you can specify
           your own custom failure message there.


  FindPackageMessage
        

       FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

       This macro is intended to be used in FindXXX.cmake modules files.  It
       will print a message once for each unique find result.  This is useful
       for telling the user where a package was found.  The first argument
       specifies the name (XXX) of the package.  The second argument
       specifies the message to display.  The third argument lists details
       about the find result so that if they change the message will be
       displayed again.  The macro also obeys the QUIET argument to the
       find_package command.

       Example:

         IF(X11_FOUND)
           FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
             "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
         ELSE(X11_FOUND)
          ...
         ENDIF(X11_FOUND)


  FindPerl
       Find perl

       this module looks for Perl

         PERL_EXECUTABLE - the full path to perl
         PERL_FOUND      - If false, don't attempt to use perl.


  FindPerlLibs
       Find Perl libraries

       This module finds if PERL is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PERL_INCLUDE_PATH = path to where perl.h is found
         PERL_EXECUTABLE   = full path to the perl binary

       


  FindPhysFS
        

       Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of
       the library to link against PHYSFS_FOUND, if false, do not try to link
       to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h

       $PHYSFSDIR is an environment variable that would correspond to the
       ./configure --prefix=$PHYSFSDIR used in building PHYSFS.

       Created by Eric Wing.

  FindPike
       Find Pike

       This module finds if PIKE is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PIKE_INCLUDE_PATH       = path to where program.h is found
         PIKE_EXECUTABLE         = full path to the pike binary

       


  FindPkgConfig
       a pkg-config module for CMake

       

       Usage:

          pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
            checks for all the given modules

       

          pkg_search_module(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
            checks for given modules and uses the first working one

       

       When the 'REQUIRED' argument was set, macros will fail with an error
       when module(s) could not be found

       It sets the following variables:

          PKG_CONFIG_FOUND         ... true if pkg-config works on the system
          PKG_CONFIG_EXECUTABLE    ... pathname of the pkg-config program
          <PREFIX>_FOUND           ... set to 1 if module(s) exist

       

       For the following variables two sets of values exist; first one is the
       common one and has the given PREFIX.  The second set contains flags
       which are given out when pkgconfig was called with the '--static'
       option.

          <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
          <XPREFIX>_LIBRARY_DIRS   ... the paths of the libraries (w/o the '-L')
          <XPREFIX>_LDFLAGS        ... all required linker flags
          <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
          <XPREFIX>_INCLUDE_DIRS   ... the '-I' preprocessor flags (w/o the '-I')
          <XPREFIX>_CFLAGS         ... all required cflags
          <XPREFIX>_CFLAGS_OTHER   ... the other compiler flags

       

          <XPREFIX> = <PREFIX>        for common case
          <XPREFIX> = <PREFIX>_STATIC for static linking

       

       There are some special variables whose prefix depends on the count of
       given modules.  When there is only one module, <PREFIX> stays
       unchanged.  When there are multiple modules, the prefix will be
       changed to <PREFIX>_<MODNAME>:

          <XPREFIX>_VERSION    ... version of the module
          <XPREFIX>_PREFIX     ... prefix-directory of the module
          <XPREFIX>_INCLUDEDIR ... include-dir of the module
          <XPREFIX>_LIBDIR     ... lib-dir of the module

       

          <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
          <XPREFIX> = <PREFIX>_<MODNAME>

       

       A <MODULE> parameter can have the following formats:

          {MODNAME}            ... matches any version
          {MODNAME}>={VERSION} ... at least version <VERSION> is required
          {MODNAME}={VERSION}  ... exactly version <VERSION> is required
          {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

       

       Examples

          pkg_check_modules (GLIB2   glib-2.0)

       

          pkg_check_modules (GLIB2   glib-2.0>=2.10)
            requires at least version 2.10 of glib2 and defines e.g.
              GLIB2_VERSION=2.10.3

       

          pkg_check_modules (FOO     glib-2.0>=2.10 gtk+-2.0)
            requires both glib2 and gtk2, and defines e.g.
              FOO_glib-2.0_VERSION=2.10.3
              FOO_gtk+-2.0_VERSION=2.8.20

       

          pkg_check_modules (XRENDER REQUIRED xrender)
            defines e.g.:
              XRENDER_LIBRARIES=Xrender;X11
              XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

       

          pkg_search_module (BAR     libxml-2.0 libxml2 libxml>=2)


  FindProducer
        

       Though Producer isn't directly part of OpenSceneGraph, its primary
       user is OSG so I consider this part of the Findosg* suite used to find
       OpenSceneGraph components.  You'll notice that I accept OSGDIR as an
       environment path.

       Each component is separate and you must opt in to each module.  You
       must also opt into OpenGL (and OpenThreads?) as these modules won't do
       it for you.  This is to allow you control over your own system piece
       by piece in case you need to opt out of certain components or change
       the Find behavior for a particular module (perhaps because the default
       FindOpenGL.cmake module doesn't work with your system as an example).
       If you want to use a more convenient module that includes everything,
       use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake
       modules.

       Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND,
       if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where
       to find the headers

       $PRODUCER_DIR is an environment variable that would correspond to the
       ./configure --prefix=$PRODUCER_DIR used in building osg.

       This module finds if Python interpreter is installed and determines
       where the executables are.  This code sets the following variables:

         PYTHONINTERP_FOUND - Was the Python executable found
         PYTHON_EXECUTABLE  - path to the Python interpreter

       


  FindPythonLibs
       Find python libraries

       This module finds if Python is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PYTHONLIBS_FOUND     = have the Python libs been found
         PYTHON_LIBRARIES     = path to the python library
         PYTHON_INCLUDE_PATH  = path to where Python.h is found
         PYTHON_DEBUG_LIBRARIES = path to the debug library

       


  FindQt
       Searches for all installed versions of QT.

       This should only be used if your project can work with multiple
       versions of QT.  If not, you should just directly use FindQt4 or
       FindQt3.  If multiple versions of QT are found on the machine, then
       The user must set the option DESIRED_QT_VERSION to the version they
       want to use.  If only one version of qt is found on the machine, then
       the DESIRED_QT_VERSION is set to that version and the matching FindQt3
       or FindQt4 module is included.  Once the user sets DESIRED_QT_VERSION,
       then the FindQt3 or FindQt4 module is included.

         QT_REQUIRED if this is set to TRUE then if CMake can 
                     not find QT4 or QT3 an error is raised 
                     and a message is sent to the user.

       

         DESIRED_QT_VERSION OPTION is created
         QT4_INSTALLED is set to TRUE if qt4 is found.
         QT3_INSTALLED is set to TRUE if qt3 is found.


  FindQt3
       Locate Qt include paths and libraries

       This module defines:

         QT_INCLUDE_DIR - where to find qt.h, etc.
         QT_LIBRARIES   - the libraries to link against to use Qt.
         QT_DEFINITIONS - definitions to use when
                          compiling code that uses Qt.
         QT_FOUND       - If false, don't try to use Qt.

       

       If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
       TRUE

       Also defined, but not for general use are:

         QT_MOC_EXECUTABLE, where to find the moc tool.
         QT_UIC_EXECUTABLE, where to find the uic tool.
         QT_QT_LIBRARY, where to find the Qt library.
         QT_QTMAIN_LIBRARY, where to find the qtmain
          library. This is only required by Qt3 on Windows.


  FindQt4
       Find QT 4

       This module can be used to find Qt4.  The most important issue is that
       the Qt4 qmake is available via the system path.  This qmake is then
       used to detect basically everything else.  This module defines a
       number of key variables and macros.  First is QT_USE_FILE which is the
       path to a CMake file that can be included to compile Qt 4 applications
       and libraries.  By default, the QtCore and QtGui libraries are loaded.
       This behavior can be changed by setting one or more of the following
       variables to true before doing INCLUDE(${QT_USE_FILE}):

                           QT_DONT_USE_QTCORE
                           QT_DONT_USE_QTGUI
                           QT_USE_QT3SUPPORT
                           QT_USE_QTASSISTANT
                           QT_USE_QTDESIGNER
                           QT_USE_QTMOTIF
                           QT_USE_QTMAIN
                           QT_USE_QTNETWORK
                           QT_USE_QTNSPLUGIN
                           QT_USE_QTOPENGL
                           QT_USE_QTSQL
                           QT_USE_QTXML
                           QT_USE_QTSVG
                           QT_USE_QTTEST
                           QT_USE_QTUITOOLS
                           QT_USE_QTDBUS
                           QT_USE_QTSCRIPT
                           QT_USE_QTASSISTANTCLIENT
                           QT_USE_QTHELP
                           QT_USE_QTWEBKIT
                           QT_USE_QTXMLPATTERNS
                           QT_USE_PHONON

       

       The file pointed to by QT_USE_FILE will set up your compile
       environment by adding include directories, preprocessor defines, and
       populate a QT_LIBRARIES variable containing all the Qt libraries and
       their dependencies.  Add the QT_LIBRARIES variable to your
       TARGET_LINK_LIBRARIES.

       Typical usage could be something like:

          FIND_PACKAGE(Qt4)
          SET(QT_USE_QTXML 1)
          INCLUDE(${QT_USE_FILE})
          ADD_EXECUTABLE(myexe main.cpp)
          TARGET_LINK_LIBRARIES(myexe ${QT_LIBRARIES})

       

       

       There are also some files that need processing by some Qt tools such
       as moc and uic.  Listed below are macros that may be used to process
       those files.

         
         macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
               create moc code from a list of files containing Qt class with
               the Q_OBJECT declaration.  Per-direcotry preprocessor definitions 
               are also added.  Options may be given to moc, such as those found
               when executing "moc -help".  

       

         macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
               create code from a list of Qt designer ui files.
               Options may be given to uic, such as those found
               when executing "uic -help"

       

         macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
               create code from a list of Qt resource files.
               Options may be given to rcc, such as those found
               when executing "rcc -help"

       

         macro QT4_GENERATE_MOC(inputfile outputfile )
               creates a rule to run moc on infile and create outfile.
               Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
               because you need a custom filename for the moc file or something similar.

       

         macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
               This macro is still experimental.
               It can be used to have moc automatically handled.
               So if you have the files foo.h and foo.cpp, and in foo.h a 
               a class uses the Q_OBJECT macro, moc has to run on it. If you don't
               want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
               #include "foo.moc"
               in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
               scan all listed files at cmake-time for such included moc files and if it finds
               them cause a rule to be generated to run moc at build time on the 
               accompanying header file foo.h.
               If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

       

         macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
               create a the interface header and implementation files with the 
               given basename from the given interface xml file and add it to 
               the list of sources

       

         macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
               create the interface header and implementation files 
               for all listed interface xml files
               the name will be automatically determined from the name of the xml file

       

         macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] )
               create a dbus adaptor (header and implementation file) from the xml file
               describing the interface, and add it to the list of sources. The adaptor
               forwards the calls to a parent class, defined in parentheader and named
               parentclassname. The name of the generated files will be
               <basename>adaptor.{cpp,h} where basename is the basename of the xml file.

       

         macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] )
               generate the xml interface file from the given header.
               If the optional argument interfacename is omitted, the name of the 
               interface file is constructed from the basename of the header with
               the suffix .xml appended.

       

         macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ... 
                                       ts_files ... OPTIONS ...)
               out: qm_files
               in:  directories sources ts_files
               options: flags to pass to lupdate, such as -extensions to specify
               extensions for a directory scan.
               generates commands to create .ts (vie lupdate) and .qm
               (via lrelease) - files from directories and/or sources. The ts files are 
               created and/or updated in the source tree (unless given with full paths).
               The qm files are generated in the build tree.
               Updating the translations can be done by adding the qm_files
               to the source list of your library/executable, so they are
               always updated, or by adding a custom target to control when
               they get updated/generated.

       

         macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
               out: qm_files
               in:  ts_files
               generates commands to create .qm from .ts - files. The generated
               filenames can be found in qm_files. The ts_files
               must exists and are not updated in any way.

                          You do not need to use this if you include QT_USE_FILE.
                          The QT_USE_FILE will also define QT_DEBUG and QT_NO_DEBUG
                          to fit your current build type.  Those are not contained
                          in QT_DEFINITIONS.

       The Qt toolkit may contain both debug and release libraries.  In that
       case, the following library variables will contain both.  You do not

       $QUICKTIME_DIR is an environment variable that would correspond to the
       ./configure --prefix=$QUICKTIME_DIR

  FindRuby
       Find Ruby

       This module finds if Ruby is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         RUBY_INCLUDE_PATH = path to where ruby.h can be found
         RUBY_EXECUTABLE   = full path to the ruby binary
         RUBY_LIBRARY      = full path to the ruby library


  FindSDL
        

       Locate SDL library This module defines SDL_LIBRARY, the name of the
       library to link against SDL_FOUND, if false, do not try to link to SDL
       SDL_INCLUDE_DIR, where to find SDL.h

       This module responds to the the flag: SDL_BUILDING_LIBRARY If this is
       defined, then no SDL_main will be linked in because only applications
       need main().  Otherwise, it is assumed you are building an application
       and this module will attempt to locate and set the the proper link
       flags as part of the returned SDL_LIBRARY variable.

       Don't forget to include SDLmain.h and SDLmain.m your project for the
       OS X framework based version.  (Other versions link to -lSDLmain which
       this module will try to find on your behalf.) Also for OS X, this
       module will automatically add the -framework Cocoa on your behalf.

       

       Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
       configuration and no SDL_LIBRARY, it means CMake did not find your SDL
       library (SDL.dll, libsdl.so, SDL.framework, etc).  Set
       SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
       Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this
       value as appropriate.  These values are used to generate the final
       SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY
       does not get created.

       

       $SDLDIR is an environment variable that would correspond to the
       ./configure --prefix=$SDLDIR used in building SDL.  l.e.galup 9-20-02

       Modified by Eric Wing.  Added code to assist with automated building
       by using environmental variables and providing a more
       controlled/consistent search behavior.  Added new modifications to
       recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
       Also corrected the header search path to follow "proper" SDL
       guidelines.  Added a search for SDLmain which is needed by some
       platforms.  Added a search for threads which is needed by some
       platforms.  Added needed compile switches for MinGW.

       On OSX, this will prefer the Framework version (if found) over others.
       People will have to manually change the cache values of SDL_LIBRARY to
       override this selection or set the CMake environment
       CMAKE_INCLUDE_PATH to modify the search paths.

       Note that the header path has changed from SDL/SDL.h to just SDL.h
       This needed to change because "proper" SDL convention is #include
       "SDL.h", not <SDL/SDL.h>.  This is done for portability reasons
       because not all systems place things in SDL/ (see FreeBSD).

  FindSDL_image
        

       Locate SDL_image library This module defines SDLIMAGE_LIBRARY, the
       name of the library to link against SDLIMAGE_FOUND, if false, do not
       try to link to SDL SDLIMAGE_INCLUDE_DIR, where to find SDL/SDL.h

       $SDLDIR is an environment variable that would correspond to the
       ./configure --prefix=$SDLDIR used in building SDL.

       Created by Eric Wing.  This was influenced by the FindSDL.cmake
       module, but with modifications to recognize OS X frameworks and
       additional Unix paths (FreeBSD, etc).

  FindSDL_mixer
        

       Locate SDL_mixer library This module defines SDLMIXER_LIBRARY, the
       name of the library to link against SDLMIXER_FOUND, if false, do not
       try to link to SDL SDLMIXER_INCLUDE_DIR, where to find SDL/SDL.h

       $SDLDIR is an environment variable that would correspond to the

  FindSDL_net
        

       Locate SDL_net library This module defines SDLNET_LIBRARY, the name of
       the library to link against SDLNET_FOUND, if false, do not try to link
       against SDLNET_INCLUDE_DIR, where to find the headers

       $SDLDIR is an environment variable that would correspond to the

  FindSWIG
       Find SWIG

       This module finds an installed SWIG.  It sets the following variables:

         SWIG_FOUND - set to true if SWIG is found
         SWIG_DIR - the directory where swig is installed
         SWIG_EXECUTABLE - the path to the swig executable
         SWIG_VERSION   - the version number of the swig executable

       

       All informations are collected from the SWIG_EXECUTABLE so the version
       to be found can be changed from the command line by means of setting
       SWIG_EXECUTABLE


  FindSelfPackers
       Find upx

       This module looks for some executable packers (i.e.  softwares that
       compress executables or shared libs into on-the-fly self-extracting
       executables or shared libs.  Examples:

         UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html


  FindSubversion
       Extract information from a subversion working copy

       The module defines the following variables:

         Subversion_SVN_EXECUTABLE - path to svn command line client
         Subversion_VERSION_SVN - version of svn command line client
         Subversion_FOUND - true if the command line client was found

       If the command line client executable is found the macro

         Subversion_WC_INFO(<dir> <var-prefix>)

       is defined to extract information of a subversion working copy at a
       given location.  The macro defines the following variables:

         <var-prefix>_WC_URL - url of the repository (at <dir>)
         <var-prefix>_WC_ROOT - root url of the repository
         <var-prefix>_WC_REVISION - current revision
         <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
         <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
         <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
         <var-prefix>_WC_LAST_CHANGED_LOG - last log of base revision
         <var-prefix>_WC_INFO - output of command `svn info <dir>'

       Example usage:

         FIND_PACKAGE(Subversion)
         IF(Subversion_FOUND)
           Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
           MESSAGE("Current revision is ${Project_WC_REVISION}")
           Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
           MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}")
         ENDIF(Subversion_FOUND)


  FindTCL
       TK_INTERNAL_PATH was removed.

       This module finds if Tcl is installed and determines where the include
       files and libraries are.  It also determines what the name of the
       library is.  This code sets the following variables:

         TCL_FOUND              = Tcl was found
         TK_FOUND               = Tk was found
         TCLTK_FOUND            = Tcl and Tk were found
         TCL_LIBRARY            = path to Tcl library (tcl tcl80)
         TCL_INCLUDE_PATH       = path to where tcl.h can be found
         TCL_TCLSH              = path to tclsh binary (tcl tcl80)
         TK_LIBRARY             = path to Tk library (tk tk80 etc)
         TK_INCLUDE_PATH        = path to where tk.h can be found
         TK_WISH                = full path to the wish executable

       

       In an effort to remove some clutter and clear up some issues for
       people who are not necessarily Tcl/Tk gurus/developpers, some
       variables were moved or removed.  Changes compared to CMake 2.4 are:

          => they were only useful for people writing Tcl/Tk extensions.
          => these libs are not packaged by default with Tcl/Tk distributions. 
             Even when Tcl/Tk is built from source, several flavors of debug libs
             are created and there is no real reason to pick a single one
             specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx). 
             Let's leave that choice to the user by allowing him to assign 
             TCL_LIBRARY to any Tcl library, debug or not.
          => this ended up being only a Win32 variable, and there is a lot of
             confusion regarding the location of this file in an installed Tcl/Tk
             tree anyway (see 8.5 for example). If you need the internal path at
             this point it is safer you ask directly where the *source* tree is
             and dig from there.


  FindTIFF
       Find TIFF library

       Find the native TIFF includes and library This module defines

         TIFF_INCLUDE_DIR, where to find tiff.h, etc.
         TIFF_LIBRARIES, libraries to link against to use TIFF.
         TIFF_FOUND, If false, do not try to use TIFF.

       also defined, but not for general use are

         TIFF_LIBRARY, where to find the TIFF library.


  FindTclStub
       TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.

       This module finds Tcl stub libraries.  It first finds Tcl include
       files and libraries by calling FindTCL.cmake.  How to Use the Tcl
       Stubs Library:

          http://tcl.activestate.com/doc/howto/stubs.html

       Using Stub Libraries:

          http://safari.oreilly.com/0130385603/ch48lev1sec3

       This code sets the following variables:

         TCL_STUB_LIBRARY       = path to Tcl stub library
         TK_STUB_LIBRARY        = path to Tk stub library

       

       In an effort to remove some clutter and clear up some issues for
       people who are not necessarily Tcl/Tk gurus/developpers, some
       variables were moved or removed.  Changes compared to CMake 2.4 are:

             Let's leave that choice to the user by allowing him to assign 
             TCL_STUB_LIBRARY to any Tcl library, debug or not.


  FindTclsh
       Find tclsh

       This module finds if TCL is installed and determines where the include
       files and libraries are.  It also determines what the name of the
       library is.  This code sets the following variables:

         TCLSH_FOUND = TRUE if tclsh has been found
         TCL_TCLSH = the path to the tclsh executable

       In cygwin, look for the cygwin version first.  Don't look for it later
       to avoid finding the cygwin version on a Win32 build.

  FindThreads
       This module determines the thread library of the system.

       The following variables are set

         CMAKE_THREAD_LIBS_INIT     - the thread library
         CMAKE_USE_SPROC_INIT       - are we using sproc?
         CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
         CMAKE_USE_PTHREADS_INIT    - are we using pthreads
         CMAKE_HP_PTHREADS_INIT     - are we using hp pthreads

       This module looks for some usual Unix commands.


  FindVTK
       Find a VTK installation or build tree.

       The following variables are set if VTK is found.  If VTK is not found,
       VTK_FOUND is set to false.

         VTK_FOUND         - Set to true when VTK is found.
         VTK_USE_FILE      - CMake file to use VTK.
         VTK_MAJOR_VERSION - The VTK major version number.
         VTK_MINOR_VERSION - The VTK minor version number 
                              (odd non-release).
         VTK_BUILD_VERSION - The VTK patch level 
                              (meaningless for odd minor).
         VTK_INCLUDE_DIRS  - Include directories for VTK
         VTK_LIBRARY_DIRS  - Link directories for VTK libraries
         VTK_KITS          - List of VTK kits, in CAPS 
                             (COMMON,IO,) etc.
         VTK_LANGUAGES     - List of wrapped languages, in CAPS
                             (TCL, PYHTON,) etc.

       The following cache entries must be set by the user to locate VTK:

         VTK_DIR  - The directory containing VTKConfig.cmake.  
                    This is either the root of the build tree,
                    or the lib/vtk directory.  This is the 
                    only cache entry.

       The following variables are set for backward compatibility and should
       not be used in new code:

         USE_VTK_FILE - The full path to the UseVTK.cmake file.
                        This is provided for backward 
                        compatibility.  Use VTK_USE_FILE 
                        instead.

       


  FindWget
       Find wget

       This module looks for wget.  This module defines the following values:

         WGET_EXECUTABLE: the full path to the wget tool.
         WGET_FOUND: True if wget has been found.


  FindWish
       Find wish installation

       This module finds if TCL is installed and determines where the include
       files and libraries are.  It also determines what the name of the
       library is.  This code sets the following variables:

         TK_WISH = the path to the wish executable

       

       if UNIX is defined, then it will look for the cygwin version first

  FindX11

         X11_FOUND        - True if X11 is available
         X11_INCLUDE_DIR  - include directories to use X11
         X11_LIBRARIES    - link against these to use X11

       

       and also the following more fine grained variables: Include paths:
       X11_ICE_INCLUDE_PATH, X11_ICE_LIB, X11_ICE_FOUND

  FindXMLRPC
       Find xmlrpc

       Find the native XMLRPC headers and libraries.

         XMLRPC_INCLUDE_DIRS      - where to find xmlrpc.h, etc.
         XMLRPC_LIBRARIES         - List of libraries when using xmlrpc.
         XMLRPC_FOUND             - True if xmlrpc found.

       XMLRPC modules may be specified as components for this find module.
       Modules may be listed by running "xmlrpc-c-config".  Modules include:

         c++            C++ wrapper code
         libwww-client  libwww-based client
         cgi-server     CGI-based server
         abyss-server   ABYSS-based server

       Typical usage:

         FIND_PACKAGE(XMLRPC REQUIRED libwww-client)


  FindZLIB
       Find zlib

       Find the native ZLIB includes and library

         ZLIB_INCLUDE_DIR - where to find zlib.h, etc.
         ZLIB_LIBRARIES   - List of libraries when using zlib.
         ZLIB_FOUND       - True if zlib found.


  Findosg
        

       This is part of the Findosg* suite used to find OpenSceneGraph
       components.  Each component is separate and you must opt in to each
       module.  You must also opt into OpenGL and OpenThreads (and Producer
       if needed) as these modules won't do it for you.  This is to allow you
       control over your own system piece by piece in case you need to opt
       out of certain components or change the Find behavior for a particular

  FindosgDB
        

       This is part of the Findosg* suite used to find OpenSceneGraph
       components.  Each component is separate and you must opt in to each
       module.  You must also opt into OpenGL and OpenThreads (and Producer
       if needed) as these modules won't do it for you.  This is to allow you
       control over your own system piece by piece in case you need to opt
       out of certain components or change the Find behavior for a particular
       module (perhaps because the default FindOpenGL.cmake module doesn't

  FindwxWidgets
       Find a wxWidgets (a.k.a., wxWindows) installation.

       This module finds if wxWidgets is installed and selects a default
       configuration to use.  wxWidgets is a modular library.  To specify the
       modules that you will use, you need to name them as components to the
       package:

       FIND_PACKAGE(wxWidgets COMPONENTS base core ...)

       There are two search branches: a windows style and a unix style.  For
       windows, the following variables are searched for and set to defaults
       in case of multiple choices.  Change them if the defaults are not
       desired (i.e., these are the only variables you should change to
       select a configuration):

         wxWidgets_ROOT_DIR      - Base wxWidgets directory
                                   (e.g., C:/wxWidgets-2.6.3).
         wxWidgets_LIB_DIR       - Path to wxWidgets libraries
                                   (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
         wxWidgets_CONFIGURATION - Configuration to use
                                   (e.g., msw, mswd, mswu, mswunivud, etc.)

       

       For unix style it uses the wx-config utility.  You can select between
       debug/release, unicode/ansi, universal/non-universal, and
       static/shared in the QtDialog or ccmake interfaces by turning ON/OFF
       the following variables:

         wxWidgets_USE_DEBUG
         wxWidgets_USE_UNICODE
         wxWidgets_USE_UNIVERSAL
         wxWidgets_USE_STATIC
         

       The following are set after the configuration is done for both windows
       and unix style:

         wxWidgets_FOUND            - Set to TRUE if wxWidgets was found.
         wxWidgets_INCLUDE_DIRS     - Include directories for WIN32
                                      i.e., where to find "wx/wx.h" and
                                      "wx/setup.h"; possibly empty for unices.
         wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
         wxWidgets_LIBRARY_DIRS     - compile time link dirs, useful for
                                      rpath on UNIX. Typically an empty string
                                      in WIN32 environment.
         wxWidgets_DEFINITIONS      - Contains defines required to compile/link
                                      against WX, e.g. -DWXUSINGDLL
         wxWidgets_CXX_FLAGS        - Include dirs and ompiler flags for
                                      unices, empty on WIN32. Esentially
                                      "`wx-config --cxxflags`".
         wxWidgets_USE_FILE         - Convenience include file.

       

       Sample usage:

          FIND_PACKAGE(wxWidgets COMPONENTS base core gl net)
          IF(wxWidgets_FOUND)
            INCLUDE(${wxWidgets_USE_FILE})
            # and for each of your dependant executable/library targets:
            TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
          ENDIF(wxWidgets_FOUND)

       

       If wxWidgets is required (i.e., not an optional part):

          FIND_PACKAGE(wxWidgets REQUIRED base core gl net)
          INCLUDE(${wxWidgets_USE_FILE})
          # and for each of your dependant executable/library targets:
          TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})


  FindwxWindows
       Find wxWindows (wxWidgets) installation

       This module finds if wxWindows/wxWidgets is installed and determines
       where the include files and libraries are.  It also determines what
       the name of the library is.  Please note this file is DEPRECATED and
       replaced by FindwxWidgets.cmake.  This code sets the following
       variables:

         WXWINDOWS_FOUND     = system has WxWindows

                               "wx-config --libs"
         CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows,
                                      essentially "`wx-config --cxxflags`"
                                      on Linux
         WXWINDOWS_INCLUDE_DIR      = where to find "wx/wx.h" and "wx/setup.h"
         WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
                                       Unix
         WXWINDOWS_DEFINITIONS      = extra defines

       

       OPTIONS If you need OpenGL support please

         SET(WXWINDOWS_USE_GL 1)

       in your CMakeLists.txt *before* you include this file.

         HAVE_ISYSTEM      - true required to replace -I by -isystem on g++

       GetPrerequisites.cmake

       This script provides functions to list the .dll, .dylib or .so files
       that an executable or shared library file depends on.  (Its
       prerequisites.)

       It uses various tools to obtain the list of required shared library
       files:

          dumpbin (Windows)
          ldd (Linux/Unix)
          otool (Mac OSX)

       

       The following functions are provided by this script:

          gp_append_unique
          gp_file_type
          is_file_executable
          gp_item_default_embedded_path
            (projects can override with gp_item_default_embedded_path_override)
          gp_resolve_item
            (projects can override with gp_resolve_item_override)
          get_prerequisites
          list_prerequisites
          list_prerequisites_by_glob

       

       Requires CMake 2.6 or greater because it uses function, break, return
       and PARENT_SCOPE.

  InstallRequiredSystemLibraries
        

       By including this file, all files in the
       CMAKE_INSTALL_DEBUG_LIBRARIES, will be installed with INSTALL_PROGRAMS
       into /bin for WIN32 and /lib for non-win32.  If
       CMAKE_SKIP_INSTALL_RULES is set to TRUE before including this file,
       then the INSTALL command is not called.  The use can use the variable
       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install command and
       install them into any directory they want.  If it is the MSVC
       compiler, then the microsoft run time libraries will be found add
       automatically added to the CMAKE_INSTALL_DEBUG_LIBRARIES, and
       installed.  If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC
       compiler, then the debug libraries are installed when available.  If
       CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are
       installed as well as the CRT run time libraries.

  UseEcos
       This module defines variables and macros required to build eCos
       application.

       This file contains the following macros:
       ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs
       ECOS_ADD_EXECUTABLE(name source1 ...  sourceN ) - create an eCos
       executable ECOS_ADJUST_DIRECTORY(VAR source1 ...  sourceN ) - adjusts
       the path of the source files and puts the result into VAR

       Macros for selecting the toolchain: ECOS_USE_ARM_ELF_TOOLS() - enable
       the ARM ELF toolchain for the directory where it is called
       ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the
       directory where it is called ECOS_USE_PPC_EABI_TOOLS() - enable the
       PowerPC toolchain for the directory where it is called

       It contains the following variables: ECOS_DEFINITIONS
       ECOSCONFIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your

          SWIG_LINK_LIBRARIES(name [ libraries ])
            - Link libraries to swig module

       All other macros are for internal use only.  To get the actual name of
       the swig module, use: ${SWIG_MODULE_name_REAL_NAME}.  Set Source files
       properties such as CPLUSPLUS and SWIG_FLAGS to specify special

------------------------------------------------------------------------------
Policies

  CMP0000
       A minimum required CMake version must be specified.

       CMake requires that projects specify the version of CMake to which
       they have been written.  This policy has been put in place so users
       trying to build the project may be told when they need to update their
       CMake.  Specifying a version also helps the project build with CMake
       versions newer than that specified.  Use the cmake_minimum_required
       command at the top of your main CMakeLists.txt file:

         cmake_minimum_required(VERSION <major>.<minor>)

       where "<major>.<minor>" is the version of CMake you want to support
       (such as "2.6").  The command will ensure that at least the given
       version of CMake is running and help newer versions be compatible with
       the project.  See documentation of cmake_minimum_required for details.

       Note that the command invocation must appear in the CMakeLists.txt
       file itself; a call in an included file is not sufficient.  However,
       the cmake_policy command may be called to set policy CMP0000 to OLD or
       NEW behavior explicitly.  The OLD behavior is to silently ignore the
       missing invocation.  The NEW behavior is to issue an error instead of
       a warning.  An included file may set CMP0000 explicitly to affect how
       this policy is enforced for the main CMakeLists.txt file.

       This policy was introduced in CMake version 2.6.0.

  CMP0001
       CMAKE_BACKWARDS_COMPATIBILITY should no longer be used.

       The OLD behavior is to check CMAKE_BACKWARDS_COMPATIBILITY and present
       it to the user.  The NEW behavior is to ignore
       CMAKE_BACKWARDS_COMPATIBILITY completely.

       In CMake 2.4 and below the variable CMAKE_BACKWARDS_COMPATIBILITY was
       used to request compatibility with earlier versions of CMake.  In
       CMake 2.6 and above all compatibility issues are handled by policies
       and the cmake_policy command.  However, CMake must still check
       CMAKE_BACKWARDS_COMPATIBILITY for projects written for CMake 2.4 and
       below.

       This policy was introduced in CMake version 2.6.0.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

  CMP0002
       Logical target names must be globally unique.

       Targets names created with add_executable, add_library, or
       add_custom_target are logical build target names.  Logical target
       names must be globally unique because:

         - Unique names may be referenced unambiguously both in CMake
           code and on make tool command lines.
         - Logical names are used by Xcode and VS IDE generators
           to produce meaningful project names for the targets.

       The logical name of executable and library targets does not have to
       correspond to the physical file names built.  Consider using the
       OUTPUT_NAME target property to create two targets with the same
       physical name while keeping logical names distinct.  Custom targets
       must simply have globally unique names (unless one uses the global
       property ALLOW_DUPLICATE_CUSTOM_TARGETS with a Makefiles generator).

       This policy was introduced in CMake version 2.6.0.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

  CMP0003
       Libraries linked via full path no longer produce linker search paths.

       This policy affects how libraries whose full paths are NOT known are
       found at link time, but was created due to a change in how CMake deals
       with libraries whose full paths are known.  Consider the code

         target_link_libraries(myexe /path/to/libA.so)

       CMake 2.4 and below implemented linking to libraries whose full paths
       are known by splitting them on the link line into separate components
       consisting of the linker search path and the library name.  The
       example code might have produced something like

         ... -L/path/to -lA ...

       in order to link to library A.  An analysis was performed to order
       multiple link directories such that the linker would find library A in
       the desired location, but there are cases in which this does not work.
       CMake versions 2.6 and above use the more reliable approach of passing
       the full path to libraries directly to the linker in most cases.  The
       example code now produces something like

         ... /path/to/libA.so ....

       Unfortunately this change can break code like

         target_link_libraries(myexe /path/to/libA.so B)

       where "B" is meant to find "/path/to/libB.so".  This code is wrong
       because the user is asking the linker to find library B but has not
       provided a linker search path (which may be added with the
       link_directories command).  However, with the old linking
       implementation the code would work accidentally because the linker
       search path added for library A allowed library B to be found.

       In order to support projects depending on linker search paths added by
       linking to libraries with known full paths, the OLD behavior for this
       policy will add the linker search paths even though they are not
       needed for their own libraries.  When this policy is set to OLD, CMake
       will produce a link line such as

         ... -L/path/to /path/to/libA.so -lB ...

       which will allow library B to be found as it was previously.  When
       this policy is set to NEW, CMake will produce a link line such as

         ... /path/to/libA.so -lB ...

       which more accurately matches what the project specified.

       The setting for this policy used when generating the link line is that
       in effect when the target is created by an add_executable or
       add_library command.  For the example described above, the code

         cmake_policy(SET CMP0003 OLD) # or cmake_policy(VERSION 2.4)
         add_executable(myexe myexe.c)
         target_link_libraries(myexe /path/to/libA.so B)

       will work and suppress the warning for this policy.  It may also be
       updated to work with the corrected linking approach:

         cmake_policy(SET CMP0003 NEW) # or cmake_policy(VERSION 2.6)
         link_directories(/path/to) # needed to find library B
         add_executable(myexe myexe.c)
         target_link_libraries(myexe /path/to/libA.so B)

       Even better, library B may be specified with a full path:

         add_executable(myexe myexe.c)
         target_link_libraries(myexe /path/to/libA.so /path/to/libB.so)

       When all items on the link line have known paths CMake does not check
       this policy so it has no effect.

       Note that the warning for this policy will be issued for at most one
       target.  This avoids flooding users with messages for every target
       when setting the policy once will probably fix all targets.

       This policy was introduced in CMake version 2.6.0.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

  CMP0004
       Libraries linked may not have leading or trailing whitespace.

       CMake versions 2.4 and below silently removed leading and trailing
       whitespace from libraries linked with code like

         target_link_libraries(myexe " A ")

       This could lead to subtle errors in user projects.

       The OLD behavior for this policy is to silently remove leading and
       trailing whitespace.  The NEW behavior for this policy is to diagnose
       the existence of such whitespace as an error.  The setting for this
       policy used when checking the library names is that in effect when the
       target is created by an add_executable or add_library command.

       This policy was introduced in CMake version 2.6.0.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

  CMP0005
       Preprocessor definition values are now escaped automatically.

       This policy determines whether or not CMake should generate escaped
       preprocessor definition values added via add_definitions.  CMake
       versions 2.4 and below assumed that only trivial values would be given
       for macros in add_definitions calls.  It did not attempt to escape
       non-trivial values such as string literals in generated build rules.
       CMake versions 2.6 and above support escaping of most values, but
       cannot assume the user has not added escapes already in an attempt to
       work around limitations in earlier versions.

       The OLD behavior for this policy is to place definition values given
       to add_definitions directly in the generated build rules without
       attempting to escape anything.  The NEW behavior for this policy is to
       generate correct escapes for all native build tools automatically.
       See documentation of the COMPILE_DEFINITIONS target property for
       limitations of the escaping implementation.

       This policy was introduced in CMake version 2.6.0.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

  CMP0006
       Installing MACOSX_BUNDLE targets requires a BUNDLE DESTINATION.

       This policy determines whether the install(TARGETS) command must be
       given a BUNDLE DESTINATION when asked to install a target with the
       MACOSX_BUNDLE property set.  CMake 2.4 and below did not distinguish
       application bundles from normal executables when installing targets.
       CMake 2.6 provides a BUNDLE option to the install(TARGETS) command
       that specifies rules specific to application bundles on the Mac.
       Projects should use this option when installing a target with the
       MACOSX_BUNDLE property set.

       The OLD behavior for this policy is to fall back to the RUNTIME
       DESTINATION if a BUNDLE DESTINATION is not given.  The NEW behavior
       for this policy is to produce an error if a bundle target is installed
       without a BUNDLE DESTINATION.

       This policy was introduced in CMake version 2.6.0.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

  CMP0007
       list command no longer ignores empty elements.

       This policy determines whether the list command will ignore empty
       elements in the list.  CMake 2.4 and below list commands ignored all
       empty elements in the list.  For example, a;b;;c would have length 3
       and not 4.  The OLD behavior for this policy is to ignore empty list
       elements.  The NEW behavior for this policy is to correctly count
       empty elements in a list.

       This policy was introduced in CMake version 2.6.0.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

  CMP0008
       Libraries linked by full-path must have a valid library file name.

       In CMake 2.4 and below it is possible to write code like

         target_link_libraries(myexe /full/path/to/somelib)

       where "somelib" is supposed to be a valid library file name such as
       "libsomelib.a" or "somelib.lib".  For Makefile generators this
       produces an error at build time because the dependency on the full
       path cannot be found.  For VS IDE and Xcode generators this used to
       work by accident because CMake would always split off the library
       directory and ask the linker to search for the library by name
       (-lsomelib or somelib.lib).  Despite the failure with Makefiles, some
       projects have code like this and build only with VS and/or Xcode.
       This version of CMake prefers to pass the full path directly to the
       native build tool, which will fail in this case because it does not
       name a valid library file.

       This policy determines what to do with full paths that do not appear
       to name a valid library file.  The OLD behavior for this policy is to
       split the library name from the path and ask the linker to search for
       it.  The NEW behavior for this policy is to trust the given path and
       pass it directly to the native build tool unchanged.

       This policy was introduced in CMake version 2.6.1.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

  CMP0009
       FILE GLOB_RECURSE calls should not follow symlinks by default.

       In CMake 2.6.1 and below, FILE GLOB_RECURSE calls would follow through
       symlinks, sometimes coming up with unexpectedly large result sets
       because of symlinks to top level directories that contain hundreds of
       thousands of files.

       This policy determines whether or not to follow symlinks encountered
       during a FILE GLOB_RECURSE call.  The OLD behavior for this policy is
       to follow the symlinks.  The NEW behavior for this policy is not to
       follow the symlinks by default, but only if FOLLOW_SYMLINKS is given
       as an additional argument to the FILE command.

       This policy was introduced in CMake version 2.6.2.  CMake version 2.6
       warns when the policy is not set and uses OLD behavior.  Use the
       cmake_policy command to set it to OLD or NEW explicitly.

------------------------------------------------------------------------------
Variables

------------------------------------------------------------------------------
Variables That Change Behavior

  BUILD_SHARED_LIBS
       Global flag to cause add_library to create shared libraries if on.

       If present and true, this will cause all libraries to be built shared
       unless the library was explicitly added as a static library.  This
       variable is often added to projects as an OPTION so that each user of
       a project can decide if they want to build the project using shared or
       static libraries.

  CMAKE_BACKWARDS_COMPATIBILITY
       Version of cmake required to build project

       From the point of view of backwards compatibility, this specifies what
       version of CMake should be supported.  By default this value is the
       version number of CMake that you are running.  You can set this to an
       older version of CMake to support deprecated commands of CMake in
       projects that were written to use older versions of CMake.  This can
       be set by the user or set at the beginning of a CMakeLists file.

  CMAKE_BUILD_TYPE
       Specifies the build type for make based generators.

       This specifies what build type will be built in this tree.  Possible
       values are empty, Debug, Release, RelWithDebInfo and MinSizeRel.  This
       variable is only supported for make based generators.  If this
       variable is supported, then CMake will also provide initial values for
       the variables with the name
       CMAKE_C_FLAGS_[Debug|Release|RelWithDebInfo|MinSizeRel].  For example,
       if CMAKE_BUILD_TYPE is Debug, then CMAKE_C_FLAGS_DEBUG will be added
       to the CMAKE_C_FLAGS.

  CMAKE_CONFIGURATION_TYPES
       Specifies the available build types.

       This specifies what build types will be available such as Debug,
       Release, RelWithDebInfo etc.  This has reasonable defaults on most
       platforms.  But can be extended to provide other build types.  See
       also CMAKE_BUILD_TYPE.

  CMAKE_FIND_LIBRARY_PREFIXES
       Prefixes to prepend when looking for libraries.

       This specifies what prefixes to add to library names when the
       find_library command looks for libraries.  On UNIX systems this is
       typically lib, meaning that when trying to find the foo library it
       will look for libfoo.

  CMAKE_FIND_LIBRARY_SUFFIXES
       Suffixes to append when looking for libraries.

       This specifies what suffixes to add to library names when the
       find_library command looks for libraries.  On Windows systems this is
       typically .lib and .dll, meaning that when trying to find the foo
       library it will look for foo.dll etc.

  CMAKE_INCLUDE_PATH
       Path used for searching by FIND_FILE() and FIND_PATH().

       Specifies a path which will be used both by FIND_FILE() and
       FIND_PATH().  Both commands will check each of the contained
       directories for the existence of the file which is currently searched.
       By default it is empty, it is intended to be set by the project.  See
       also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_PREFIX_PATH.

  CMAKE_INSTALL_PREFIX
       Install directory used by install.

       If "make install" is invoked or INSTALL is built, this directory is
       pre-pended onto all install directories.  This variable defaults to
       /usr/local on UNIX and c:/Program Files on Windows.

  CMAKE_LIBRARY_PATH
       Path used for searching by FIND_LIBRARY().

       Specifies a path which will be used by FIND_LIBRARY().  FIND_LIBRARY()
       will check each of the contained directories for the existence of the
       library which is currently searched.  By default it is empty, it is
       intended to be set by the project.  See also
       CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.

  CMAKE_MFC_FLAG
       Tell cmake to use MFC for an executable or dll.

       This can be set in a CMakeLists.txt file and will enable MFC in the
       application.  It should be set to 1 for static the static MFC library,
       and 2 for the shared MFC library.  This is used in visual studio 6 and
       7 project files.  The CMakeSetup dialog uses MFC and the
       CMakeLists.txt looks like this:

       ADD_DEFINITIONS(-D_AFXDLL)

       set(CMAKE_MFC_FLAG 2)

       add_executable(CMakeSetup WIN32 ${SRCS})


  CMAKE_MODULE_PATH
       Path to look for cmake modules to load.

       Specifies a path to override the default seach path for CMake modules.
       For example include commands will look in this path first for modules
       to include.

  CMAKE_NOT_USING_CONFIG_FLAGS
       Skip _BUILD_TYPE flags if true.

       This is an internal flag used by the generators in CMake to tell CMake
       to skip the _BUILD_TYPE flags.

  CMAKE_PREFIX_PATH
       Path used for searching by FIND_XXX(), with appropriate suffixes
       added.

       Specifies a path which will be used by the FIND_XXX() commands.  It
       contains the "base" directories, the FIND_XXX() commands append
       appropriate subdirectories to the base directories.  So FIND_PROGRAM()
       adds /bin to each of the directories in the path, FIND_LIBRARY()
       appends /lib to each of the directories, and FIND_PATH() and
       FIND_FILE() append /include .  By default it is empty, it is intended
       to be set by the project.  See also CMAKE_SYSTEM_PREFIX_PATH,
       CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.

  CMAKE_PROGRAM_PATH
       Path used for searching by FIND_PROGRAM().

       Specifies a path which will be used by FIND_PROGRAM().  FIND_PROGRAM()
       will check each of the contained directories for the existence of the
       program which is currently searched.  By default it is empty, it is
       intended to be set by the project.  See also
       CMAKE_SYSTEM_PROGRAM_PATH, CMAKE_PREFIX_PATH.

  CMAKE_SYSTEM_INCLUDE_PATH
       Path used for searching by FIND_FILE() and FIND_PATH().

       Specifies a path which will be used both by FIND_FILE() and
       FIND_PATH().  Both commands will check each of the contained
       directories for the existence of the file which is currently searched.
       By default it contains the standard directories for the current
       system.  It is NOT intended to be modified by the project, use
       CMAKE_INCLUDE_PATH for this.  See also CMAKE_SYSTEM_PREFIX_PATH.

  CMAKE_SYSTEM_LIBRARY_PATH
       Path used for searching by FIND_LIBRARY().

       Specifies a path which will be used by FIND_LIBRARY().  FIND_LIBRARY()
       will check each of the contained directories for the existence of the
       library which is currently searched.  By default it contains the
       standard directories for the current system.  It is NOT intended to be
       modified by the project, use CMAKE_SYSTEM_LIBRARY_PATH for this.  See
       also CMAKE_SYSTEM_PREFIX_PATH.

  CMAKE_SYSTEM_PREFIX_PATH
       Path used for searching by FIND_XXX(), with appropriate suffixes
       added.

       Specifies a path which will be used by the FIND_XXX() commands.  It
       contains the "base" directories, the FIND_XXX() commands append
       appropriate subdirectories to the base directories.  So FIND_PROGRAM()
       adds /bin to each of the directories in the path, FIND_LIBRARY()
       appends /lib to each of the directories, and FIND_PATH() and
       FIND_FILE() append /include .  By default this contains the standard
       directories for the current system.  It is NOT intended to be modified
       by the project, use CMAKE_PREFIX_PATH for this.  See also
       CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_SYSTEM_LIBRARY_PATH,
       CMAKE_SYSTEM_PROGRAM_PATH.

  CMAKE_SYSTEM_PROGRAM_PATH
       Path used for searching by FIND_PROGRAM().

       Specifies a path which will be used by FIND_PROGRAM().  FIND_PROGRAM()
       will check each of the contained directories for the existence of the
       program which is currently searched.  By default it contains the
       standard directories for the current system.  It is NOT intended to be
       modified by the project, use CMAKE_PROGRAM_PATH for this.  See also
       CMAKE_SYSTEM_PREFIX_PATH.

  CMAKE_USER_MAKE_RULES_OVERRIDE
       Specify a file that can change the build rule variables.

       If this variable is set, it should to point to a CMakeLists.txt file
       that will be read in by CMake after all the system settings have been
       set, but before they have been used.  This would allow you to override
       any variables that need to be changed for some special project.

------------------------------------------------------------------------------
Variables That Describe the System

  APPLE
       True if running on Mac OSX.

       Set to true on Mac OSX.

  BORLAND
       True of the borland compiler is being used.

       This is set to true if the Borland compiler is being used.

  CMAKE_CL_64
       Using the 64 bit compiler from Microsoft

       Set to true when using the 64 bit cl compiler from Microsoft.

       True for Apple OSXoperating systems.

       Set to true when the host system is Apple OSX.

  CMAKE_HOST_SYSTEM
       Name of system cmake is being run on.

       The same as CMAKE_SYSTEM but for the host system instead of the target
       system when cross compiling.

  CMAKE_HOST_SYSTEM_NAME
       Name of the OS CMake is running on.

       The same as CMAKE_SYSTEM_NAME but for the host system instead of the
       target system when cross compiling.

  CMAKE_HOST_SYSTEM_PROCESSOR
       The name of the CPU CMake is running on.

       The same as CMAKE_SYSTEM_PROCESSOR but for the host system instead of
       the target system when cross compiling.

  CMAKE_HOST_SYSTEM_VERSION
       OS version CMake is running on.

       The same as CMAKE_SYSTEM_VERSION but for the host system instead of
       the target system when cross compiling.

  CMAKE_HOST_UNIX
       True for UNIX and UNIX like operating systems.

       True on windows systems, including win64.

       Set to true when the host system is Windows and on cygwin.

  CMAKE_OBJECT_PATH_MAX
       Maximum object file full-path length allowed by native build tools.

       CMake computes for every source file an object file name that is
       unique to the source file and deterministic with respect to the full
       path to the source file.  This allows multiple source files in a
       target to share the same name if they lie in different directories
       without rebuilding when one is added or removed.  However, it can
       produce long full paths in a few cases, so CMake shortens the path
       using a hashing scheme when the full path to an object file exceeds a
       limit.  CMake has a built-in limit for each platform that is
       sufficient for common tools, but some native tools may have a lower
       limit.  This variable may be set to specify the limit explicitly.  The
       value must be an integer no less than 128.

       This variable is the composite of CMAKE_SYSTEM_NAMEand
       CMAKE_SYSTEM_VERSION, like this
       ${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}.  If CMAKE_SYSTEM_VERSION
       is not set, then CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.

  CMAKE_SYSTEM_NAME
       Name of the OS CMake is building for.

       This is the name of the operating system on which CMake is targeting.
       On systems that have the uname command, this variable is set to the
       output of uname -s.  Linux, Windows, and Darwin for Mac OSX are the
       values found on the big three operating systems.

  CMAKE_SYSTEM_PROCESSOR
       The name of the CPU CMake is building for.

       On systems that support uname, this variable is set to the output of
       uname -p, on windows it is set to the value of the environment
       variable PROCESSOR_ARCHITECTURE

  CMAKE_SYSTEM_VERSION
       OS version CMake is building for.

       A numeric version string for the system, on systems that support
       uname, this variable is set to the output of uname -r.  On other
       systems this is set to major-minor version numbers.

  CYGWIN
       True for cygwin.

       Set to true when using CYGWIN.

  MSVC
       True when using Microsoft Visual C

       Set to true when the compiler is some version of Microsoft Visual C.

       opposed to the command line compiler.

  MSVC_VERSION
       The version of Microsoft Visual C/C++ being used if any.

       The version of Microsoft Visual C/C++ being used if any.  For example
       1300 is MSVC 6.0.

  UNIX
       True for UNIX and UNIX like operating systems.

       Set to true when the target system is UNIX or UNIX like (i.e.  APPLE
       and CYGWIN).

  WIN32
       True on windows systems, including win64.

       Set to true when the target system is Windows and on cygwin.

       any variables that need to be changed for some language.

------------------------------------------------------------------------------
Variables that Control the Build

  CMAKE_ARCHIVE_OUTPUT_DIRECTORY
       Where to put all the ARCHIVE targets when built.

       This variable is used to initialize the ARCHIVE_OUTPUT_DIRECTORY
       property on all the targets.  See that target property for additional
       information.

  CMAKE_BUILD_WITH_INSTALL_RPATH
       Use the install path for the RPATH

       Normally CMake uses the build tree for the RPATH when building
       executables etc on systems that use RPATH.  When the software is
       installed the executables etc are relinked by CMake to have the
       install RPATH.  If this variable is set to true then the software is
       always built with the install path for the RPATH and does not need to
       be relinked when installed.

  CMAKE_DEBUG_POSTFIX
       A postfix to add to targets when build as debug.

       This variable is used to initialize the DEBUG_POSTFIX property on all
       the targets.  If set the postfix will be appended to any targets built
       when the configuration is Debug.

  CMAKE_EXE_LINKER_FLAGS
       Linker flags used to create executables.

       Flags used by the linker when creating an executable.

  CMAKE_EXE_LINKER_FLAGS_[CMAKE_BUILD_TYPE]
       Flag used when linking an executable.

       Same as CMAKE_C_FLAGS_* but used by the linker when creating
       executables.

  CMAKE_Fortran_MODULE_DIRECTORY
       Fortran module output directory.

       This variable is used to initialize the Fortran_MODULE_DIRECTORY
       property on all the targets.  See that target property for additional
       information.

  CMAKE_INSTALL_NAME_DIR
       Mac OSX directory name for installed targets.

       CMAKE_INSTALL_NAME_DIR is used to initialize the INSTALL_NAME_DIR
       property on all targets.  See that target property for more
       information.

  CMAKE_INSTALL_RPATH
       The rpath to use for installed targets.

       A semicolon-separated list specifying the rpath to use in installed
       targets (for platforms that support it).  This is used to initialize
       the target property INSTALL_RPATH for all targets.

  CMAKE_INSTALL_RPATH_USE_LINK_PATH
       Add paths to linker search and installed rpath.

       CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true
       will append directories in the linker search path and outside the
       project to the INSTALL_RPATH.  This is used to initialize the target
       property INSTALL_RPATH_USE_LINK_PATH for all targets.

  CMAKE_LIBRARY_OUTPUT_DIRECTORY
       Where to put all the LIBRARY targets when built.

       This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY
       property on all the targets.  See that target property for additional
       information.

  CMAKE_LIBRARY_PATH_FLAG
       The flag used to add a library search path to a compiler.

       The flag used to specify a library directory to the compiler.  On most
       compilers this is "-L".

  CMAKE_LINK_DEF_FILE_FLAG  
       Linker flag used to specify a .def file for dll creation.

       The flag used to add a .def file when creating a dll on Windows, this
       is only defined on Windows.

  CMAKE_LINK_LIBRARY_FILE_FLAG
       Flag used to link a library specified by a path to its file.

       The flag used before a library file path is given to the linker.  This
       is needed only on very few platforms.

  CMAKE_LINK_LIBRARY_FLAG
       Flag used to link a library into an executable.

       The flag used to specify a library to link to an executable.  On most
       compilers this is "-l".

  CMAKE_RUNTIME_OUTPUT_DIRECTORY
       Where to put all the RUNTIME targets when built.

       This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY
       property on all the targets.  See that target property for additional
       information.

  CMAKE_SKIP_BUILD_RPATH
       Do not include RPATHs in the build tree.

       Normally CMake uses the build tree for the RPATH when building
       executables etc on systems that use RPATH.  When the software is
       installed the executables etc are relinked by CMake to have the
       install RPATH.  If this variable is set to true then the software is
       always built with no RPATH.

  CMAKE_USE_RELATIVE_PATHS
       Use relative paths (May not work!).

       If this is set to TRUE, then the CMake will use relative paths between
       the source and binary tree.  This option does not work for more
       complicated projects, and relative paths are used when possible.  In
       general, it is not possible to move CMake generated makefiles to a
       different location regardless of the value of this variable.

  EXECUTABLE_OUTPUT_PATH
       Old executable location variable.

       This variable should no longer be used as of CMake 2.6.  Use the
       RUNTIME_OUTPUT_DIRECTORY target property instead.  It will override
       this variable if it is set.

       If set, this is the directory where all executables built during the
       build process will be placed.

  LIBRARY_OUTPUT_PATH
       Old library location variable.

       This variable should no longer be used as of CMake 2.6.  Use the
       ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
       RUNTIME_OUTPUT_DIRECTORY target properties instead.  They will
       override this variable if they are set.

       If set, this is the directory where all the libraries built during the
       build process will be placed.

------------------------------------------------------------------------------
Variables that Provide Information

variables defined by cmake, that give information about the project, and
cmake

  CMAKE_AR
       Name of archiving tool for static libraries.

       This specifies name of the program that creates archive or static
       libraries.

  CMAKE_BINARY_DIR
       The path to the top level of the build tree.

       This is the full path to the top level of the current CMake build
       tree.  For an in-source build, this would be the same as
       CMAKE_SOURCE_DIR.

  CMAKE_BUILD_TOOL
       Tool used for the acutal build process.

       This variable is set to the program that will be needed to build the
       output of CMake.  If the generator selected was Visual Studio 6, the
       CMAKE_MAKE_PROGRAM will be set to msdev, for Unix makefiles it will be
       set to make or gmake, and for Visual Studio 7 it set to devenv.  For
       Nmake Makefiles the value is nmake.  This can be useful for adding
       special flags and commands based on the final build environment.

  CMAKE_CACHEFILE_DIR
       The directory with the CMakeCache.txt file.

       This is the full path to the directory that has the CMakeCache.txt
       file in it.  This is the same as CMAKE_BINARY_DIR.

  CMAKE_CACHE_MAJOR_VERSION
       Major version of CMake used to create the CMakeCache.txt file

       This is stores the major version of CMake used to write a CMake cache
       file.  It is only different when a different version of CMake is run
       on a previously created cache file.

  CMAKE_CACHE_MINOR_VERSION
       Minor version of CMake used to create the CMakeCache.txt file

       This is stores the minor version of CMake used to write a CMake cache
       file.  It is only different when a different version of CMake is run
       on a previously created cache file.

  CMAKE_CACHE_RELEASE_VERSION
       Release version of CMake used to create the CMakeCache.txt file

       This is stores the release version of CMake used to write a CMake
       cache file.  It is only different when a different version of CMake is
       run on a previously created cache file.

  CMAKE_CFG_INTDIR
       Build time configuration directory for project.

       This is a variable that is used to provide developers access to the
       intermediate directory used by Visual Studio IDE projects.  For
       example, if building Debug all executables and libraries end up in a
       Debug directory.  On UNIX systems this variable is set to ".".
       However, with Visual Studio this variable is set to $(IntDir).
       $(IntDir) is expanded by the IDE only.  So this variable should only
       be used in custom commands that will be run during the build process.
       This variable should not be used directly in a CMake command.  CMake
       has no way of knowing if Debug or Release will be picked by the IDE
       for a build type.  If a program needs to know the directory it was
       built in, it can use CMAKE_INTDIR.  CMAKE_INTDIR is a C/C++
       preprocessor macro that is defined on the command line of the
       compiler.  If it has a value, it will be the intermediate directory
       used to build the file.  This way an executable or a library can find
       files that are located in the build directory.

  CMAKE_COMMAND
       The full path to the cmake executable.

       This is the full path to the CMake executable cmake which is useful
       from custom commands that want to use the cmake -E option for portable
       system commands.  (e.g.  /usr/local/bin/cmake

  CMAKE_CROSSCOMPILING
       Is CMake currently cross compiling.

       This variable will be set to true by CMake if CMake is cross
       compiling.  Specifically if the build platform is different from the
       target platform.

  CMAKE_CTEST_COMMAND
       Full path to ctest command installed with cmake.

       This is the full path to the CTest executable ctest which is useful
       from custom commands that want to use the cmake -E option for portable
       system commands.

  CMAKE_CURRENT_BINARY_DIR
       The path to the binary directory currently being processed.

       This the full path to the build directory that is currently being
       processed by cmake.  Each directory added by add_subdirectory will
       create a binary directory in the build tree, and as it is being
       processed this variable will be set.  For in-source builds this is the
       current source directory being processed.

  CMAKE_CURRENT_LIST_FILE
       Full path to the listfile currently being processed.

       As CMake processes the listfiles in your project this variable will
       always be set to the one currently being processed.  See also
       CMAKE_PARENT_LIST_FILE.

  CMAKE_CURRENT_LIST_LINE
       The line number of the current file being processed.

       This is the line number of the file currently being processed by
       cmake.

  CMAKE_CURRENT_SOURCE_DIR
       The path to the source directory currently being processed.

       The suffix to use for the end of a loadable module on this platform

  CMAKE_SIZEOF_VOID_P
       Size of a void pointer.

       This is set to the size of a pointer on the machine, and is determined
       by a try compile.  If a 64 bit size is found, then the library search
       path is modified to look for 64 bit libraries first.

  CMAKE_SKIP_RPATH
       If true, do not add run time path information.

       If this is set to TRUE, then the rpath information is not added to
       compiled executables.  The defaultis to add rpath information if the
       platform supports it.This allows for easy running from the build tree.

  CMAKE_SOURCE_DIR
       The path to the top level of the source tree.

       This is the full path to the top level of the current CMake source
       tree.  For an in-source build, this would be the same as
       CMAKE_BINARY_DIR.

  CMAKE_STANDARD_LIBRARIES

       This is set to true if the compiler is Visual Studio free tools.

  CMAKE_VERBOSE_MAKEFILE
       Create verbose makefiles if on.

       This variable defaults to false.  You can set this variable to true to
       make CMake produce verbose makefiles that show each command line as it
       is used.

  PROJECT_BINARY_DIR
       Full path to build directory for project.

       This is the binary directory of the most recent PROJECT command.

  PROJECT_NAME
       Name of the project given to the project command.

       This is the name given to the most recent PROJECT command.

  PROJECT_SOURCE_DIR
       Top level source directory for the current project.

       This is the source directory of the most recent PROJECT command.

  [Project name]_BINARY_DIR
       Top level binary directory for the named project.

       A variable is created with the name used in the PROJECT command, and
       is the binary directory for the project.  This can be useful when
       SUBDIR is used to connect several projects.

  [Project name]_SOURCE_DIR
       Top level source directory for the named project.

       A variable is created with the name used in the PROJECT command, and
       is the source directory for the project.  This can be useful when
