# libSupport can be embedded in use cases where we don't want to load all
# cl::opt unless we want to parse the command line.
# ManagedStatic can be used to enable lazy-initialization of globals.
# We don't use `add_flag_if_supported` as instead of compiling an empty file we
# check if the current platform is able to compile global std::mutex with this
# flag (Linux can, Darwin can't for example).
