[vtkusers] VTK compilation with QT

Mon Mar 24 17:27:41 EDT 2014

Hi

that’s because QT5 support is only available since VTK 6.1. So the option is not present in VTK 6.0.

In this regard, I checked out the VTK using "git clone git://vtk.org/VTK.git VTK", and then when I ran ccmake in the command line, I saw the VTK_QT_VERSION listed, and I set it to 5. After setting the rest of ccmake parameters, it worked and I complied VTK with Qt-enabled.
