Yep! Agreed.

Sounds like a good plan to me. I think the code changes will be straightforward at this point, at least in LLD.

Yeah, this is going to be a bit tricky, I guess. In that case, we need to expose that flag in clang-cl as well - it's not perfect, but I don't have a better idea at this point.

I'll start by changing this patch to include the base dir to the search paths.
