[Paraview] PV 5.3-RC.2 build error on macOS 10.12

[Fabian Wein]

I raised the following issue: https://gitlab.kitware.com/paraview/paraview-superbuild/issues/47

First I build the current superbuild master on macOS 10.12 which built PV 5.2 with qt 5.8.0 without problems. Then I switched the source to PV 5.3-RC.2 and got the following error

 89%] Building CXX object Qt/Core/CMakeFiles/pqCore.dir/moc_pqRepresentation.cpp.o
/Users/fwein/code/cfs_paraview/manual_53/build/superbuild/paraview/build/Qt/Core/moc_pqQVTKWidget.cpp:85:8: error: use of undeclared identifier 'QVTKWidget'; did you mean 'pqQVTKWidget'?
    { &QVTKWidget::staticMetaObject, qt_meta_stringdata_pqQVTKWidget.data,
