Review Comment:
   It should be able to be run anywhere as long as gRPC is on your `PKG_CONFIG_PATH`. If you have installed grpc via package manager then it will be. Otherwise you might have to add a build directory to that path. If you try to run the command and `grpc` isn't on the path, `pkg-config` will provide an error message saying it's not found and you should check your `PKG_CONFIG_PATH`.
