Glium is a convenient choice, but is a rather big dependency which compiles slowly, and uses build.rs. It is also no longer actively maintained.

The ideal choice for compiling Egui natively would be something simple that compiles quickly. I'm not sure there is such an alternative though.

One alternative worth investigating is pure glutin (which Glium depend on). It is a bit lower level compared to Glium, and requires use of unsafe, but it looks easy enough to use: https://gist.github.com/matthewjberger/9da00592b472b50ec1e6b3238719264b
