Hmm … does the file llvm-project/llvm/cmake/modules/GenerateVersionFromVCS.cmake exist? Can you `git pull`, and does `git status` show any changes?

Judging by this path: needed by 'tools/lld/Common/VCSVersion.inc' It looks to me like this is **not** a monorepo layout (if it were, lld would not appear in the tools directory). Therefore the LLVM_ENABLE_PROJECTS=lld is not even doing anything. I don't know how to build without a monorepo these days, and I also don't know what the most recent guidance setting up a monorepo is, but maybe someone else can chime in.
