+# 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.
