`Makefile` does not find existing `SDL.h`.

[dreirund]

When I run make, it complains that it cannot find SDL.h:

In file included from ui_state.h:4,
                 from tool_core.h:7,
                 from actions.cpp:1:
gui.h:5:10: fatal error: SDL.h: No such file or directory
    5 | #include "SDL.h"
      |          ^~~~~~~
compilation terminated.

But I have in my system:

/usr/include/SDL/SDL.h
/usr/include/SDL2/SDL.h

Seems that you need to add some code that finds where the stuff is installed.

Regards!

Here I attach a patch that changes the SDL include by prepending SDL/: fix-sdl-include-path.patch.txt.
