The 'include' keyword makes the compiler look for header files in
$C_INCLUDE_PATH and a few other locations.  The Guix daemon will populate
that variable with all inputs that have an "include" directory.  Running
`guix build sdl2-mixer` shows that it has ".../include/SDL2/SDL_mixer.h".

What's needed here is to make sure SDL_USEFOLDER is set such that it
searches for <SDL2/SDL_mixer.h> as on line 58.  Alternatively, you could
substitute the code on line 63 to read 'include "SDL2/SDL_mixer.h"' as a
probably dirty workaround.

HTH!
