# - Find ThreadingBuildingBlocks include dirs and libraries
# Use this module by invoking find_package with the form:
#  find_package(TBB
#    [REQUIRED]             # Fail with error if TBB is not found
#    )                      #
# Once done, this will define
#
#  TBB_FOUND - system has TBB
#  TBB_INCLUDE_DIRS - the TBB include directories
#  TBB_LIBRARIES - TBB libraries to be lined, doesn't include malloc or
#                  malloc proxy
#  TBB::tbb - imported target for the TBB library
#
#  TBB_VERSION_MAJOR - Major Product Version Number
#  TBB_VERSION_MINOR - Minor Product Version Number
#  TBB_INTERFACE_VERSION - Engineering Focused Version Number
#  TBB_COMPATIBLE_INTERFACE_VERSION - The oldest major interface version
#                                     still supported. This uses the engineering
#                                     focused interface version numbers.
#
#  TBB_MALLOC_FOUND - system has TBB malloc library
#  TBB_MALLOC_INCLUDE_DIRS - the TBB malloc include directories
#  TBB_MALLOC_LIBRARIES - The TBB malloc libraries to be lined
#  TBB::malloc - imported target for the TBB malloc library
#
#  TBB_MALLOC_PROXY_FOUND - system has TBB malloc proxy library
#  TBB_MALLOC_PROXY_INCLUDE_DIRS = the TBB malloc proxy include directories
#  TBB_MALLOC_PROXY_LIBRARIES - The TBB malloc proxy libraries to be lined
#  TBB::malloc_proxy - imported target for the TBB malloc proxy library
#
#
# This module reads hints about search locations from variables:
#  ENV TBB_ARCH_PLATFORM - for eg. set it to "mic" for Xeon Phi builds
#  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
