I think the llvm-core recipe is effectively unmaintained at this point. It hasn't been touched in almost a year, and besides that, LLVM is on version 17 and the latest version of the llvm-core recipe is 13. I can't even build this recipe with Conan v1 right now. We might see a more comprehensive llvm package if #17509 ever gets through. Until then, someone will need to step up and update this recipe if that's desired. I know I need a better solution for a dependency on LLVM in #20528.
