I notice the problem is gRPC_PROTOBUF_PROVIDER is "module" but PROTOBUF_ROOT_DIR is wrong . How can i fix this?

[Kixunil]

Looks like a dupliate of #92
Anyway, should be fixed by #83

[csunny]

@Kixunil Yes, I fixed this by myself. I reinstall cmake with verion 3 and reinstall protobuf. Thanks very much. I run some code with client.
