Description Simon Zeni 2020-12-18 14:46:37 UTC 
On Alpinelinux, where the DirectFB backend is enabled in the package itself (https://git.alpinelinux.org/aports/tree/community/sdl2/APKBUILD#n53), several CMake projects that uses SDL2's SDL2Targets.cmake will fail to build with the following error

In file included from /home/simon/dev/FNA3D/src/FNA3D_Driver_OpenGL.c:33:
/usr/include/SDL2/SDL_syswm.h:80:10: fatal error: directfb.h: No such file or directory
   80 | #include <directfb.h>
      |          ^~~~~~~~~~~~

The build is successful if SDL2 is found through pkgconfig.
