Don’t you just need to add darwin.ps to your buildInputs? It’s propagated by cmake if you use the normal stdenv.

That seems to do the trick, thank you! As cmake seems to rely on ps being available (or else it outputs that message) should it not be specified as an input to cmake?

It is: https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/tools/build-managers/cmake/default.nix#L63

But you need to use Nixpkgs stdenv for propagation to work.

That makes sense, thanks for taking the time to explain!
