Nix + IDE Integration
If your IDE reports that a file doesn't belong to the project or that files cannot be found, the CMake cache is likely missing the Nix-provided paths.
This may happen when the IDE runs CMake on its own, outside the Nix environment, leaving the required paths empty.
Preferred fix: launch the IDE from inside the Nix dev shell
This makes the IDE inherit required environment variables directly, so every CMake reload it triggers has the right environment, not just a one-off cache snapshot.
Example:
nix develop -c ...
Or, if you're using CLion, there's already a shortcut for that:
just clion
Alternative: regenerate the cache, then reload without resetting it
If you don't want to launch the IDE from inside the Nix dev shell, you can try to reuse an existing CMakeCache.txt on
reload instead of always re-running cmake with its own environment.
To do that, you first need to regenerate the cache. This can be done by running:
nix develop -c just configure
Then reload the CMake project without resetting the cache (resetting it would wipe the paths you just wrote):
JetBrains: View → Tool Windows → CMake → Reload ↺
This won't help on an IDE that always re-invokes cmake with its own (non-Nix) environment on reload.
