Without access to the code (externals/cmake-modules/FindSDL2.cmake in this case)
I can't really help debug it.

My guess is that the custom FindSDL2 module is doing something wrong
when it tries to find the SDL2 header files.
It doesn't seem to search in all system include paths.
The headers have been moved from /usr/include/SDL2 to /usr/include/<arch>/SDL2.

Cheers,
