When a program is installed in your environment, these libraries should be found automatically. However, this is not the case in a `nix-shell`.

'''Note:''' Both of these approaches are impure and only work to a certain degree (many limitations!). If you want to use a different version of Mesa your best option is to use an overlay or a Git worktree where you use the same Nixpkgs revision and only alter <code>pkgs/development/libraries/mesa/</code> for one of the two approaches mentioned above. | '''Note:''' Both of these approaches are impure and only work to a certain degree (many limitations!).
