I'm trying to rebuild FreeCAD but I've run into the following and I don't know how to fix it.

The bundled copy of PyCXX defines PYCXX_PYTHON_2TO3 which in turn causes some Python 2 compatibility things to be defined, like Py::Int. So this broke when moving to using the unbundled copy of PyCXX. I submitted a PR with a fix: https://src.fedoraproject.org/rpms/freecad/pull-request/4
