Hey Luca,

so as I take it the SDL2 headers are properly found and you can "jump into" 
(i.e. Ctrl+Click on "#include <SDL2/SDL.h>") them, right?

In your case it looks like none of the function mentioned could be found 
(they're not colored in blue, like e.g. "SDL_GetError()").

In case only some functions are not detected, then the problems is likely that 
their declaration is could not be parsed properly. Could you jump into SDL.h 
or SDL_surface.h and check whether SDL_LoadBMP/SDL_LoadBMP_RW could not be 
parsed properly?

To me it looks like all the structs like SDL_Texture/SDL_Surface cannot be 
parsed and thus cause follow up errors everywhere.
