libGL.so is available through libglvnd.

running Minecraft from an IDE to develop mods no longer works, failing with an OpenGL exception:

To make this library available, you can use LD_LIBRARY_PATH which can extend the default locations for glibc to look for dynamic libraries. To do this, you want to run something like export LD_LIBRARYPATH="${LD_LIBRARY_PATH}${LD_LIBRARY_PATH:+:}/nix/store/yw48bqgswppkcrx303ybgbn6r2nqbda1-libglvnd-1.7.0/lib

Ideally, this would take the form of using nix develop:

# devShell.nix or shell.nix
{ mkShell
, libglvnd
...
}:

mkShell {
...
  shellHook = ''
    export LD_LIBRARY_PATH="''${LD_LIBRARY_PATH}''${LD_LIBRARY_PATH:+:}${libglvnd}/lib"
  '';
}
