# This macro gets the version string for a compiler, and also extracts
# compiler flags.

# Parameters:
#   LANGUAGE       - C or CXX, the compiler to check for
#   BUILD_COMPILER - [output variable] string with compiler path, ID and
#                    some compiler-provided information
#   BUILD_FLAGS    - [output variable] flags for the compiler
#
