[vtk-developers] Add pugixml to VTK

[David Thompson]

>> I am working on a CityGML reader for VTK. For this I need a fast XML parser. pugixml is already used by ParaView and seems to be much faster than available choices already present in VTK: libxml2 and expat. pugixml has also a very clean API.

I thought Ben Boeckel was working on a removing as many things from ThirdParty as possible (and making them parts of a superbuild). So perhaps the CityGML reader should live in a VTK module that requires an external pugi? I know pugi is small, but...
