[vtkusers] libQVTK.so: undefined reference

[David Gobbi]

Hi Agupta,

Not sure why CMake isn't catching it as a dependency of QVTK, but you
can try adding this before your link line:

SET(QT_LIBRARIES ${QT_LIBRARIES} QtXmlPatterns)

This is not supposed to be necessary because CMake should take care
of this for you.  If you look in your VTK build directory, there should be a
file called VTKLibraryDepends.cmake, and it should list QtXmlPatterns
as part of the QVTK_LIB_DEPENDS line.  Can you check to see if it is
there?

  David
