Thank you, @Thomas! That solved the drivers part of my question. @Bruce: If you have too much time on your hands, and want to experiment with set theory on Meson, you could implement a "longest prefix match" for this, making the narrower selection take precedence. Just kidding! Enabling/disabling drivers as Thomas described works great. Still, a similar Meson option for selecting libraries would be nice.
