I think it would make sense if cc.find_library had extra arguments that
would be added to the dependency and, in case of compile_args, to the
has_headers check.  It's a tradeoff between keeping the language simple
and making the users' code smaller.

Another possible extension is for cc.links to allow internal
dependencies, as long as they do not depend on sources.
