I got as far as you did following your instructions. I can follow the steps to get a SDL .a build with Wayland support. However, running the engine (even after fully rebuilding it) does indeed not use our Wayland-enabled SDL2, as it still fails to run. I can force it to use my system SDL2 lib by defining SDL_DYNAMIC_API=/usr/share/libSDL2.so, but it crashes shortly after opening the initial project list window. My attempt to get it working is documented here: Mat: "@PJB thanks! This does get it to run on Wayland, …" - Gamedev Mastodon
