[vtkusers] QVTKWidget in QTCreator - runtime error in Debug

[Michael Lynch]

Thanks Clinton,
This solved my problem. Just for posterity, to solve the problem I set
CMAKE_BUILD_TYPE to Debug. Then I configured, generated, 'mingw32-make'd and
'mingw32-make install'd.

This created a set of debug dlls which work wonderfully with QTCreator and
qmake. I kept the old 'Release' dlls and use the flags
win32:release:LIBS += ....
win32:debug:LIBS += ....


Thanks again,
Michael
