I think there are two ways you could solve this:
Wraps are probably the most generically correct method; what I mean by that is
that a proper wrap would solve the problem for everyone, on every operating
system, forever. That said, I took a look at GLEW and it doesn't look like a
straightforward project to port to meson, since it uses a huge pile of gnu
makefiles for compilation, without any autoconf/cmake/etc. I still might take a
swing at it since I want to know how hard it would be to write a wrap file for
something like GLEW (and it would probably be a pretty useful project to wrap)
where a meson build system is likely never going to go upstream.
The other option I think you can use use is cross properties[1], which I believe
is the closest thing meson has to cmake's cache files.
I've pushed a couple of commits, the last one implements the cross properties
idea, which gets the build farther, but then it can't find the glut headers,
and I don't understand why, since "cc.has_header('GL/glut')" returns true. I
still think that wraps are a better plan, but I'll have to spend some time today
working on a glew wrap.
