+-# * TBB_ROOT_DIR          - The base directory the of TBB installation.
+-# * TBB_INCLUDE_DIR       - The directory that contains the TBB headers files.
+-# * TBB_LIBRARY           - The directory that contains the TBB library files.

+-#                           These libraries, if specified, override the

+-#                           tbb_preview, or tbb_preview_debug.
+-# * TBB_USE_DEBUG_BUILD   - The debug version of tbb libraries, if present, will
+-#                           be used instead of the release version.
+-# * TBB_STATIC            - Static linking of libraries with a _static suffix.
+-#                           For example, on Windows a tbb_static.lib will be searched for
