# Defines the following variables:
#
#   TBB_FOUND - Found the OPENCL framework
#   TBB_INCLUDE_DIRS - Include directories
#
# Also defines the library variables below as normal
# variables.  These contain debug/optimized keywords when
# a debugging library is found.

#   TBB_LIBRARY_DEBUG

#   TBB_ROOT - (as a CMake or environment variable)

#
#   FIND_LIBRARY_USE_LIB64_PATHS - Global property that controls whether findTBB should search for

#
#    add_executable(foo foo.cc)
