# - Check whether the MIC CXX compiler supports a given flag.
# CHECK_MIC_CXX_COMPILER_FLAG(<flag> <var>)
# <flag> - the compiler flag
# <var> - variable to store the result
# This internally calls the check_cxx_source_compiles macro. See help
# for CheckCXXSourceCompiles for a listing of variables that can
# modify the build.
