I have some old OCaml code that uses OpenGL. I gather OpenGL is now deprecated on Mac but I’m wondering how I might resurrect this code on my Mac?

LablGL installs but compiling my code with it fails with:

```
File "_none_", line 1:              
Error: No implementations provided for the following modules:
        Glut referenced from bin/.main.eobjs/native/dune __exe__ Main.cmx
```

Did you list `lablgl.glut` in the libraries stanza?
