Hi. I'm getting the following error when I run cabal build with LLVM 9.0.1:

...

The weird thing is that llvm/Config/llvm-config.hs does exist. To be more precise, my folder structure is the following:

llvm-project
 - build
 -- include
 --- llvm
 ---- Config
 ----- llvm-config.h
 ----- ...
 ---- ...
 -- ...
 -- myProject

and then I'm calling cabal build within myProject. I'm on Ubuntu 22.04.2 LTS, Dell XPS 13 7390. I feel obligated to note that this comes after much struggling to get llvm9.0.1 and getting cabal to use it. I'm sure that llvm-hs has accepted 9.0.1 because this comes after many "this is the wrong llvm version" error messages.
