Since update focal, libsdl2 and libsdl2-ttf headers have a different location, causing a compilation error when trying to include SDL2/SDL_ttf.h header :

$ sudo apt install libsdl2-ttf-dev libsdl2-dev
$ echo "#include <SDL2/SDL_ttf.h>" > main.c
$ gcc main.c
In file included from main.c:1:
/usr/include/SDL2/SDL_ttf.h:34:10: fatal error: SDL.h: Aucun fichier ou dossier de ce type
   34 | #include "SDL.h"
      | ^~~~~~~
compilation terminated.

It seems that SDL_ttf.h header expects to be in the same place that SDL ones, which is not the case :

$ dpkg -L libsdl2-ttf-dev
/.
/usr
/usr/include
/usr/include/SDL2
/usr/include/SDL2/SDL_ttf.h
...

$ dpkg -L libsdl2-dev
/.
/usr
/usr/bin
/usr/bin/sdl2-config
/usr/include
/usr/include/x86_64-linux-gnu
/usr/include/x86_64-linux-gnu/SDL2
/usr/include/x86_64-linux-gnu/SDL2/SDL.h
