Compilation Error on Wayland for version 0.46.0

[EriKWDev]

I'm in the process of migrating egui_glfw_gl to latest version of glfw, but getting the following error when I change to 0.46.0 release on wayland (fedora).

Compilation works with version 0.45.0. Also, if I turn off defualt-features for version 0.46.0 and only enable glfw-sys feature, compilation still works fine.

@Techniker123 maybe has any clues..?

[Frostie314159]

This isn't actually a glfw_sys issue. I ran into this to while writing the patches in #507. There is a question on superuser, that explains how to solve this: here

[EriKWDev]

That was it! I got a second error later which was resolved by also installing "wayland-protocols-devel".

Is there any official list anywhere for what dependencies are required and could/should we link to it in the README? Found this but not any more "official"

[EriKWDev]

The border looks a bit weird though and when trying to resize or move it around I get weird results (wrong side of the window scaling and so on).

Do you guys observe this behaviour as well with other apps on wayland with glfw or does this warrant a new issue? (or is this libadwaita-related..?)
