  #   CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
  #   CUDA_SDK_ROOT_DIR     -- Path to the CUDA SDK.  Use this to find files in the
  #                            SDK.  This script will not directly support finding
  #                            specific libraries or headers, as that isn't
  #                            supported by NVIDIA.  If you want to change
  #                            libraries when the path changes see the
  #                            FindCUDA.cmake script for an example of how to clear
  #                            these variables.  There are also examples of how to
  #                            use the CUDA_SDK_ROOT_DIR to locate headers or
