cannot find -lSDL2-static (or i just need help compiling)

^{_{top: mingw64 - bottom: ubuntu 20.04 wsl}}

before this i got errors relating to ./src/Backend/SDL2 not importing SDL.h properly (i got past that by changing them to SDL2/SDL.h)
i've tried resolving this issue by installing SDL2 in any other way i can and can't get this fixed at all
