Make sure to download these here files (I'm not actually sure if this works by itself anymore):
- SDL2-devel-2.30.1-VC
- SDL2-devel-2.30.1-mingw
- SDL2_image-devel-2.8.2-VC
They are automatically linked to the project if in this here directory: C:\Users%USERNAME%\SDL2 Otherwise, you have to figure it out :(
