cabal: Could not resolve dependencies:
[__0] next goal: animate-preview (user goal)
[__0] rejecting: animate-preview-0.1.2.1 (constraint from user target requires
==0.1.2)
[__0] trying: animate-preview-0.1.2
[__1] next goal: sdl2-image (dependency of animate-preview)
[__1] rejecting: sdl2-image-2.0.0, sdl2-image-0.1.3.2, sdl2-image-0.1.3.1,
sdl2-image-0.1.3.0, sdl2-image-0.1.1.0, sdl2-image-0.1.0.1 (conflict:
pkg-config package SDL2_image>=2.0.0, not found in the pkg-config database)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, animate-preview, sdl2-image
