The problem here is that the SDL header file is actually in
/include/SDL/SDL.h.  So, "SDL.h" should be "SDL/SDL.h".  To fix this,
you could add a phase to patch the source appropriately, or add a make
flag (#:make-flags in the 'arguments' package field) that adds
'(string-append (assoc-ref %build-inputs "sdl") "/include/SDL")' to the
include path.

Good luck!
