Though these are broken and error prone, as they ignore the possibility of conflicts between SDL, SDL2 and wrappers thereof discarding useful include path prefix (SDL2/), since SDL and satellite libraries follow these it's too hard to stay away. So don't use prefixes for SDL include paths any longer.
