On a second though I fear having the include files of libsdl2 and libsdl2-*
in different paths will break some build systems.

A random example I quickly found:
https://sources.debian.org/src/neverball/1.6.0+git20180603-2/Makefile/

It calls "sdl2-config --cflags" and then would fail to find SDL_ttf.h (from
the libsdl2-ttf-dev package) in /usr/include/SDL2.

One option would be to add -I/usr/include/SDL2 to sdl2-config or pkg-config
but I'm not sure if that would cover all cases.

Cheers,
