Hi :)

I think you might be missing a few steps/deps before running make. Please refer to this Dockerfile to build the plugin using Makefile (also note that after 1.2.1 we've refactored our dependencies to use third_party/protobuf directly, instead of third_party/grpc/third_party/protobuf).

(Also just curious what's the reason you need to build the plugin from scratch? :))
