I tried following the instructions at Moment’s GitHub
I tried to build it myself but I keep running into issues. Anyone able to actually package this for NixOS? I found it because it is a fork of the Mirage Matrix Client

In general when dealing with Linux CLIs, options come before positional arguments (in this case, filenames). So in your command, -lQt6Quick etc are treated as input paths. You should move them before the filenames, and all should be well.
(And yes, some of the Nix tools are cursed with putting flags after positional arguments. This seems to be a recent trend.)
So I edited the Makefile and added a space but here is the output of make:
