[PATCH] D137024: [compiler-rt] Switch from llvm-config to find_package(LLVM)

[Michał Górny via Phabricator via cfe-commits]

mgorny updated this revision to Diff 472285.
mgorny added a comment.

Add a backwards compatibility path that uses `LLVM_CONFIG_PATH` to locate LLVM CMake files. I think it's sufficient to use path relative to the specified location, and we don't want to actually call it.

Restore the explicit warning when LLVM is not found and the fallback path is used.
