It looks like you've added a class to vtkMy/Imaging that derives from 
vtkImageToImageFilter.  When it is wrapped in Tcl, the wrapper tries to 
call the wrapper of the superclass, which is defined in vtkFilteringTCL, 
so you need to link to that library as well.

Please try editing vtkMy/Imaging/CMakeLists.txt and change this line:

   TARGET_LINK_LIBRARIES (vtkmyImagingTCL vtkmyCommonTCL vtkmyImaging)

to this:

   TARGET_LINK_LIBRARIES (vtkmyImagingTCL vtkmyCommonTCL vtkmyImaging
                          vtkFilteringTCL)
