Hi! Since the version of ALVR on nixpkgs is out of date and they’re not supplying an appimage anymore, I’m trying to build ALVR again. I think I’m almost there, but I’m currently stuck on this stupid error when building:
--- stderr

I’m guessing that pipewire is built and can’t find the standard C-headers. But I’ve not succeeded in supplying those. They are in my nix store. But I couldn’t supply them yet. 
Here’s my current default.nix file (note that it’s still WIP):
