+#  TBB_VERSION_MAJOR - Major Product Version Number

-# FindTBB
-# -------
-#
-# Find TBB include directories and libraries.
-#
-# Usage:
-#
-#  find_package(TBB [major[.minor]] [EXACT]
-#               [QUIET] [REQUIRED]
-#               [[COMPONENTS] [components...]]
-#               [OPTIONAL_COMPONENTS components...])
-#
-# where the allowed components are tbbmalloc and tbb_preview. Users may modify
-# the behavior of this module with the following variables:
-#
-# * 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>
-#                           may be tbb, tbb_debug, tbbmalloc, tbbmalloc_debug,
-#                           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.
-#
-# Users may modify the behavior of this module with the following environment
-# variables:
-#
-# * TBB_INSTALL_DIR
-# * TBBROOT
-# * LIBRARY_PATH
-#
-# This module will set the following variables:
-#
-# * TBB_FOUND             - Set to false, or undefined, if we haven’t found, or
-#                           don’t want to use TBB.
-# * TBB_<component>_FOUND - If False, optional <component> part of TBB sytem is
-#                           not available.
-# * TBB_VERSION           - The full version string
-# * TBB_VERSION_MAJOR     - The major version
-# * TBB_VERSION_MINOR     - The minor version
-# * TBB_INTERFACE_VERSION - The interface version number defined in
-#                           tbb/tbb_stddef.h.
-# * TBB_<library>_LIBRARY_RELEASE - The path of the TBB release version of
-#                           <library>, where <library> may be tbb, tbb_debug,
-#                           tbbmalloc, tbbmalloc_debug, tbb_preview, or
-#                           tbb_preview_debug.
-# * TBB_<library>_LIBRARY_DEGUG - The path of the TBB release version of
-#                           <library>, where <library> may be tbb, tbb_debug,
-#                           tbbmalloc, tbbmalloc_debug, tbb_preview, or
-#                           tbb_preview_debug.
-#
-# The following varibles should be used to build and link with TBB:
-#
-# * TBB_INCLUDE_DIRS - The include directory for TBB.
-# * TBB_LIBRARIES    - The libraries to link against to use TBB.
-# * TBB_DEFINITIONS  - Definitions to use when compiling code that uses TBB.
