# file(GENERATE writes a file at Generation time. Also, it writes one
# file per detected configuration, in this case, each COMPILE_LANGUAGE
# is a new configuration.
#
# We use 'file(GENERATE' instead of configure_file because we want to
# generate the file after Configure-time to have all the
# metadata. Also, we don't use 'add_custom_command' because it cannot
# read the generator expressions that we use.
