Sorry, I've meant to get on this a little faster, but the meson conversion has
been a lot more time consuming than I predicted it would be, lol.
Meson should make that a little simpler, since it has an install target, and we
should be able to make that work for you guys as well.

I think it's pretty close to being ready for review. It's based on a branch to
fix static-glapi with meson that never landed, but I think I have that all
sorted now so I'm going to push that today, and that should make the haiku build
pretty simple (it's just one patch after that I think).

Awesome, that makes things a lot easier with meson.
You can have a look at the build in general, I think meson is syntactically
pretty nice, it's like a minimal python or ruby, and the builds are much faster
(that's just because ninja is really smart).
