python/src/sdf/_gz_sdformat_pybind11.cc:153:25: warning: 'operator()' is deprecated: Please use py::set_error() instead (https://github.com/pybind/pybind11/pull/4772) [-Wdeprecated-declarations]
      sdfErrorsException(e.what());
                        ^
/usr/local/include/pybind11/pybind11.h:2623:5: note: 'operator()' has been explicitly marked deprecated here
