Can I use other people libraries in compo?

I know this usually is a big no-no, but love2d doesn't have light functionality built in. I think of using one of these libraries: - https://github.com/matiasah/shadows - https://github.com/tanema/light_world.lua

These libraries also have some shaders built in so I guess I shouldn't use those but light... I mean people using Unity, Godot or whatever have that already so using these libraries seems justified :thinking:
