Motivation for this change

There have been some changes in kdevelop which prevented a simple version bump from compiling on NixOS. I've bumped the version and provided a fix so it will compile. I tested a brand new project with kdevelop and everything is working fine. Testing an existing project I had with kdevelop is not properly working.

I would appreciate anyone else who uses kdevelop to test this if possible and provide feedback. I'll try to follow up with kdevelop devs on troubleshooting to see what the issue might be and if it is specific to my project, or a problem with kdevelop 5.3.1 on NixOS (ie. this PR).

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Assured whether relevant documentation is up to date
  • Fits CONTRIBUTING.md.

After some digging and discussion I found the issue and it wasn't related to NixOS or my build at all. This PR is ready to merge.

Any particular reason not to use llvmPackages_latest? Is this likely to break with updates?

The llvm package provides the c++ parsing and analysis for kdevelop and different versions of llvm can dramatically impact how the application behaves. The decision to move from one version of llvm to another might not break compilation, but it could break functionality, so a person should specifically test any llvm bumps to avoid breaking behavior in the application.

Alright. Do you think this PR needs more testing? I don't use kdevelop personally.

At this point I've done enough testing I feel the PR is fine for merge.

Thanks!
