# - Check whether the CXX compiler supports a given flag.

|
# CHECK_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.
