[Insight-users] ITK in Paraview Plugin

[Christian Werner]

Luis, you led me to the right direction. Good news, everything works 
fine! By chance I found some cmake related postings where there was some 
problem with the LINK_LIBRARIES variable. I was like "Gee, this variable 
looks nice! It could replace my TARGET_LINK_LIBRARIES which does not 
work anyway." And voila, everything goes. This is what I put into my 
CMakeList that made Paraview execute my cool plugin (a itkFlipImageFilter :)

LINK_LIBRARIES( vtkITKImageBox
    ITKCommon ITKIO ITKBasicFilters
)

I know, diving a little bit more into CMake would have helped in the 
first place, but you just can't study everything before getting your 
work done.

What's a bit strange is that the plugin is very big (7MB). I am afraid 
that the vtkITKImageBox (which is about that big), or even some ITK 
stuff is cramped into the filter despite my efforts to link everything 
dynamically. I will try to find a solution to this.


Thanks for your help with everything Luis and best regards,
Christian
