Hello guys, I installed ghcide which is working great, but everytime that I do a rebuild I have to run: cat $(which ghc),
then set the newly generated nix path of NIX_GHC_LIBDIR in the in it's corresponding sessionVariable of my 
home.nix configuration, is there a way to automate this process so I don't have to keep doing this manually
over and over again?

here is an issue that someone else is having that is similar to my issue:
https://github.com/hercules-ci/ghcide-nix/issues/26

also, here is my sessionVariables code section of my home.nix configuration file:
