I think it's a lot easier to run mods with the Linux source ports and so far I've had no issues running arcane dimensions (AD).
To run that mod from a CLI with most source ports, you just need to make sure that you specify a path to your original Quake .PAK files and set the -gamedir to the path of your AD mod folder.

I downloaded the arcane dimensions mod from here: https://www.moddb.com/mods/arcane-dimensions/downloads/arcan...
I hope that helps!
