[PATCH] D85715: [clangd] Attempt to allow gRPC & Proobuf static linking

[Kirill Bobyrev via Phabricator via llvm-commits]

kbobyrev added a comment.

This is a full reproducer of what would work with grpc++ built from source. Seems like the dependencies are pulled by CMake and this way it actually links correctly.
