This seems to be handled by upstream:

    https://github.com/open-source-parsers/jsoncpp/blob/96d32b37eac518147f3d733012a6c28db3720328/src/lib_json/json_writer.cpp#L78

and our copy already has it:

    https://gitlab.kitware.com/third-party/jsoncpp/blob/master/src/lib_json/json_reader.cpp#L46

As Shawn mentioned, vtkSmartPointer is not a std::shared_ptr.
boost::intrusive_ptr would be more a more accurate replacement.
