[Insight-users] VTK_LIBRARIES empty?

[Luis Ibanez]

Hi Toon,

In InsightApplications we usually put
the explicit list of VTK libraries that
are needed by the application.

You may want to look at the CMakeLists.txt files
in the subdirectories of InsightApplications.

For example to:

    InsightApplications/
             RegionGrowingSegmentation

    InsightApplications/
             GeodesicActiveContours


that use expressions such as:


TARGET_LINK_LIBRARIES(GeodesicActiveContour
   ITKNumerics
   ITKBasicFilters
   ITKIO
   vtkHybrid
   vtkIO
   ITKVtkFltk
   ITKFltkImageViewer
)



Regards,


    Luis
