Bug#953440: libvtk7.1 does not include xdmf3 libraries

[Ruben Di Battista]

Ehi Alastair,

Sorry for the late response, but I did not get the notifications back
from the bug system.

However, despite Debian shipping xdmf3 library, it also needs to
enable it in VTK build. The current list of files of libvtk7-dev does
not list the libraries for XDMF3.

These are some libraries that needs to be present if the XDMF3 module
is enabled in VTK (in particular the ones with the 3 in the filename):

```
