Cmake assumes /bin/sh to be present when checking for working C compiler

[tim-hilt]

Describe the bug

When compiling anything via cmake with gcc, cmake will try to compile a simple test-program. However this will fail because it assumes /bin/sh to be present (instead of for example /usr/bin/env sh, which would work).

To Reproduce Steps to reproduce the behavior:

1. Include something, that will build with cmake in your configuration.nix or flake.nix
2. `nixos-rebuild switch

Expected behavior

Correct compilation resulting in a usable program

I am getting something similar with xorg font packages:

duplicate of https://github.com/NixOS/nixpkgs/issues/124372 ?

[tim-hilt]

Possibly. I can confirm it when I find out how to delete the store-path-line from /etc/nix/nix.conf.

[tim-hilt]

Confirmed this is a duplicate of #124372. Closing.
