Install OCaml with graphics on mac with homebrew 2.0.0 (-with-x11 no longer possible)

Is there an alternative way to install the graphics module for use with ocaml on mac?

Previously, I had used

brew install ocaml --with-x11

This no longer works, as the package option is no longer supported with brew 2.0.0. Is there another way to get graphics working in ocaml on Mac without this option? I am running Sierra 10.12.6, but am working with a large group running many different mac versions that all need to be able to do this install.
