Demos don't compile out of the box for wayland

[gemath]

When building for Wayland, demos/common/egl_helper.cppmust be compiled with -DSDL_VIDEO_DRIVER_WAYLAND. If the config could set that automatically, everything would work out of the box.

Hi,

I think that define is supposed to come from SDL2's SDL_config.h header. As far as I know, that define is used just in SDL_syswm.h to include the member struct that is referenced in egl_helper (specifically w.info.wl). The demos build out of the box under Ubuntu based distros and several others I have tested.

That it fails to build is quite troubling, what Linux distro does it not build under without adding the SDL_VIDEO_DRIVER_WAYLAND ?

I did a significant update: I removed the entire EGL binding system from the demos and FastUIDraw. It was made (quite some time ago) when I had encountered issues with letting SDL2 get an GLES context itself (the issue only manifested on one platform I tested and I suspect it was caused by an error I made). The upshot is that the demos transparently rely on SDL2 to do the right thing about the windowing system and getting a GL/GLES context instead of having an option to do it itself.

Let me know if this works fine for you and if it does, I will close the issue.

Sry for taking such a long time. It works for me now. In case it still matters: I use Void Linux with sway (Wayland compositor with XWayland support).
