# This is not supported on all compilers/versions. so enabling only
# for clang, since that works for all versions that our bots run.
#
# This is intentionally done after adding the external subdirectory,
# so we don't enforce this flag on our dependencies, some of which do
# not pass it.
#
# If the minimum version of CMake supported is updated to 3.0 or
# later, then check_cxx_compiler_flag could be used instead.
