But correctness trumps aesthetics. I guess where I went astray was that it appeared to work unquoted when doing a simple test with add_executable and so I standardized on unquoted which then came back to bite me unexpectedly later. I think I'm understanding better the situation thanks to your explanation combined with that link. I shall quote them all!
