vtkSocketCommunicator errors: "Could not receive tag" and "Endian handshake failed"

The --recusive option just tells the VTK submodule to update its (currently one) submodule, VTK-m, which shouldn’t make a difference with regards to the client/server handshake. But that operation should be updated in the build instructions.
