------------------------------------------------------------
rgrpc: pkg-config cannot find 'grpc++'.
  Installing WITHOUT gRPC: every call errors and
  grpc_available() returns FALSE.
  Ubuntu/Debian: sudo apt install libgrpc++-dev libprotobuf-dev
  (libgrpc++-dev, not libgrpc-dev: the C-only package leaves
   the C++ runtime and grpc++.pc missing. libgrpc++-dev does
   not pull libprotobuf-dev under --no-install-recommends.)
  Fedora: sudo dnf install grpc-cpp grpc-devel protobuf-devel
  macOS (Homebrew): brew install grpc protobuf pkgconf
