[vtkusers] ITK/VtkGlue

[Bernhard Froehler]

Hi

I have seen this problem too, both on Ubuntu and on Mac OS.
On Linux it was fixed for me by switching from Ubuntu 12.04 to 13.10, 
and accordingly from some custom-ppa Qt5 packages to the ones officially 
included in 13.10 - not sure what exactly changed to fix it - my wild 
guess would be that this is an issue with the cmake files included in Qt.
As a workaround, you can edit the file containing the reference 
(Modules/Bridge/VtkGlue/src/CMakeFiles/ITKVtkGlue.dir/link.txt). Just 
removing the offending entry (" -lQt5::Widgets") made the build run 
through fine for me.

The same problem subsequently also happened for our app relying on 
ITK/VTK/Qt; the same workaround helped there too.

Regards,
Bernhard
