# This file is included by cmGlobalGenerator::EnableLanguage.
# It is included after the compiler has been determined, so
# we know things like the compiler name and if the compiler is gnu.
# before cmake 2.6 these variables were set in cmMakefile.cxx. This is still
# done to keep scripts and custom language and compiler modules working.
# But they are reset here and set again in the platform files for the target
# platform, so they can be used for testing the target platform instead
# of testing the host platform.
