cabal: Could not resolve dependencies:
[__0] next goal: sdl2-mixer (user goal)
[__0] rejecting: sdl2-mixer-1.2.0.0 (conflict: pkg-config package
SDL2_mixer==2.0.0 || >2.0.0, not found in the pkg-config database)
[__0] rejecting: sdl2-mixer-1.1.0, sdl2-mixer-0.1 (constraint from user target
requires ==1.2.0.0)
[__0] fail (backjumping, conflict set: sdl2-mixer)
After searching the rest of the dependency tree exhaustively, these were the
