++#  ENV TBB_ROOT or just TBB_ROOT - root directory of tbb installation
++#  ENV TBB_BUILD_PREFIX - specifies the build prefix for user built tbb
++#                         libraries. Should be specified with ENV TBB_ROOT
++#                         and optionally...
++#  ENV TBB_BUILD_DIR - if build directory is different than ${TBB_ROOT}/build
+ #
+-# * 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.
+-# * TBB_<library>_LIBRARY - The path of the TBB the corresponding TBB library. 
+-#                           These libraries, if specified, override the 
+-#                           corresponding library search results, where <library>

+-#                           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
+-#                           instead of tbb.lib.
