I built gRPC from source with cmake.
I then build my client which is gRPC based with cmake.
As far as I understand the linking error I get is not related to my source code but perhaps a configuration issue. The weirder thing is that the libraries the linker complains about should be a part of the libgrpc++.a(based on gRPC cmake.)
the failed command
