[vtkusers] Using Cmake for VTK + Qt applications on a Mac

[Shakes]

Hi Shriram,

I suggest using qmake (Qt's own build tool) for your apps as Qt requires 
moc files and other things while VTK can be linked against like any 
other library. I use a .pro qmake file like the following which u may 
find useful:

TEMPLATE = app
DEPENDPATH += . ../../include
INCLUDEPATH += ../../include

unix:INCLUDEPATH += /usr/include/vtk-5.0 /usr/local/include/vtk-5.0
unix:LIBS += -lvtkRendering -lvtkFiltering -lvtkGraphics 
-lvtkVolumeRendering -lvtkHybrid -lvtkImaging -lvtkIO -lvtkCommon -lQVTK

win32-msvc2005:LIBS += vtkRendering.lib vtkFiltering.lib vtkGraphics.lib 
vtkVolumeRendering.lib vtkHybrid.lib vtkImaging.lib vtkIO.lib 
vtkCommon.lib QVTK.lib
win32-g++:LIBS += -lvtkRendering -lvtkFiltering -lvtkHybrid 
-lvtkGraphics -lvtkVolumeRendering -lvtkImaging -lvtkIO -lvtkCommon -lQVTK

CONFIG += qt warn_on release

#Needed for app to work in Windows
DEFINES    += QT_DLL

# Input
SOURCES += mainvtk.cpp

You may need to add and remove parts depending on what you're doing. 
Hope that helps.

Cheers
Shakes
