You can include the file "vtkmCellSetExplicit.h" to fix that. You might
also need to include "vtkmCellSetSingleType.h" if you see errors about
single type cellsets being undefined.

If you use the vtkm filter directly, it should work to use the
fromvtk::Convert method from Accelerators/Vtkm/vtkmlib/PolyDataConverter.h
to skip that extra step.
