David, you are right. I can successfully run the Python examples that come
with VTK after commenting out 'import qvtk' from __init__.py
But I really have no clue about what could be wrong with VTK/Qt.
I set QT_QMAKE_EXECUTABLE:FILEPATH=/tmp/yifli/bin/qmake, and all other
entries related to Qt in CMakeCache.txt seem to be generated automatically
And here is a list of QVTK related entries in my CMakeCache.txt. Any
further help is greatly appreciated.
