[Insight-users] link error when learning (Getting Started with ITK + VTK)

[Radtke, Phil]

Hello,

Working through "Getting Started with ITK + VTK (part II)", it looks to me like the vtkRendering and vtkImaging libraries are not getting linked into my project. I listed vtkRendering and vtkImaging in a TARGET_LINK_LIBRARIES definition for cmake and the library files `libvtkRendering.a' and `libvtkImaging.a' are in my vtk_binary/bin/ directory. Thanks for any help or suggestions.
