The approach I took to get this to build is pretty hacky :/

I think this needs a cmake expert to clean it up.

I tested the PR with:

gh pr checkout 189042
nix-build -A cura
./result/bin/cura

Looks quite good to me:

This badly needs someone who understands what conan and its cmake is trying to do to help clean it up or find a better approach. It's really janky right now :(

Hm, there was one on the 5.2 draft pull request, #208124. 🤔

I appreciate the effort, im new to NixOS and just installed cura only to realize its still on 4.x while we already have 5.6 .-.
Im sadly no cmake magician either, so i cant really help much. But i hope this gets updated soon, and please not only to 5.1, but 5.6

Oh, closing this was fine. I gave up on trying to tidy this up properly. 😅
