You can then remove the DLLs. The problem is: so far, everything I've written is cross platform-ish (only limited by what SDL2 can do). It offers maximum hardware accelerated performance at a minimum of resource usage and overhead. SFML is less segregated (the graphics module gives you sprites, primitives, and TTF text, the audio module gives you music, basic sound effects, and positional sound) and you can tweak the scope of your project just by SDL2 offers also IOS-Support (raylib only Android) and you can also make homebrew-ports with SDL2 for Nintendo Switch.
