This file is used by CMake when finding VTK. It provides the [VTK module
API][] as well as some VTK-specific APIs.

The following variables are provided by this module:

  * `VTK_VERSION`: The version of VTK found.
  * `VTK_MAJOR_VERSION`: The major version of VTK found.
  * `VTK_MINOR_VERSION`: The minor version of VTK found.
  * `VTK_BUILD_VERSION`: The build version of VTK found.
  * `VTK_AVAILABLE_COMPONENTS`: Components available with VTK.
  * `VTK_PREFIX_PATH`: Install prefix for VTK.
  * `VTK_HAS_VTKm: [Deprecated, use VTK_HAS_VISKORES] If VTK provides VTK-m.
  * `VTK_HAS_VISKORES`: If VTK provides Viskores.
  * `VTK_OPENGL_HAS_EGL`: If VTK can use EGL for OpenGL context.
  * `VTK_OPENGL_USE_GLES`: If VTK uses GLES.
  * `VTK_USE_X`: If VTK uses X windows.
  * `VTK_USE_COCOA`: If VTK uses Cocoa (only present on APPLE systems).
  * `VTK_PYTHON_VERSION`: The major version of Python used by VTK. Empty if
    Python support is not available.
  * `VTK_WRAP_PYTHON`: If VTK itself provides Python wrapping. If so, the
    Python parts of the module API are available.
  * `VTK_WRAP_JAVA`: If VTK itself provides Java wrapping. If so, the
    Java parts of the module API are available.
  * `VTK_WRAP_SERIALIZATION`: If VTK itself provides serialization wrappings
    for marshallable classes in modules with `INCLUDE_MARSHAL`.
  * `VTK_PYTHONPATH`: Where VTK's Python modules live inside the install
    prefix. Unset if Python is not available.
  * `VTK_LIBRARIES`: The list of modules specified by `COMPONENTS` and
    `OPTIONAL_COMPONENTS`. However, if no components are specified, all
    available components are added to this variable. This may be used in
    `MODULES` arguments in the API (e.g., `vtk_module_autoinit`). All modules
    are also targets and may be linked to using `target_link_libraries`.
  * `VTK_AUTOINIT_INCLUDE`: The header to include for access to VTK's autoinit
    support.
  * `VTK_QT_VERSION`: The major version of Qt used by VTK if Qt support enabled.
  * `VTK_QML_DIR`: Where VTK's QML plugins live if QML support is enabled.
  * `VTK_ENABLE_VR_COLLABORATION`: Is VR collaboration enabled when VR is enabled.
  * `VTK_SMP_BACKENDS`: The list of available SMP backends.

For more information about the Python in use by VTK, (note that the `Python`
component must be found to guarantee that this happens), see the
[FindPython3][] documentation for what is available. Of particular use are
likely to be:

  - the `Python3_VERSION` variable; and
  - the `Python3::Python` target.
