wayland being installed causes linker with SDL to fail

[llight3]

this was with the latest code on a basic compile in both x11 and wayland with SDL_VIDEODRIVER=x11 and SDL_VIDEODRIVER=wayland
all error messages were with WAYLAND_wl_proxy_something
both 32bit and 64bit versions tried

A workaround for this is to set the SDL_version in build_deps.sh to the sdl2 version installed on your pc for me this meant i moved from
SDL_version=2.0.9 to SDL_version=2.0.12

[la-ninpre]

i've encountered the same issue and workaround for me was to just pass all dependencies from my system, so

cmake .. -DENABLE_SDL2=ON -DENABLE_SOUND=ON -DENABLE_FLUIDSYNTH=ON -DENABLE_OPENGL=ON

note: ah, yes, im building inside another directory, not in the source tree, hence .. in cmake invocation.
