title: '"SDL.h" no such file or directory found' when compiling
body: <p>Here's a piece of my current Makefile:</p>
  
  <pre><code>CFLAGS = -O2 -Wall -pedantic -std=gnu++11 `sdl-config --cflags --libs` -lSDL_mixer
  </code></pre>
  
  <p>I have libsdl installed properly, SDL.h is in /usr/include/sdl where it belongs, but it just won't compile. I also have the line <code>#include "SDL.h"</code> in my .h files, but still no go.</p>
  
  <p>Anyone knows why?</p>
