This is one of the first times I’ve spent quite a bit of time on building a package (3 days).
I’ve gotten it to build but openvr_mw (the main binary) is unable to find libEGL. export LD_LIBRARY_PATH in shell lets it find libEGL but it’s unable to find libuuid after and trying to add it to LD_LIBRARY_PATH doesn’t seem to work.
I’ve tried patchelf, runtimeDependencies, putting it in buildDependencies, etc.
I’d take any advice on how to fix this or just packaging in general, what I’ve done wrong (ex. the flake callPackage is really ugly, and i need to substituteInPlace the ${openxr-sdk} openxr.pc.in correctly instead of forking it)
Since there’s no other distro repos that have this package, I think it could benefit a lot of people outside of NixOS and even possibly introduce people to Nix.
