|  | # 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. |
