See the undefined references in vtk library ibvtkRendering.a. This 
library depends on another vtk library which needs to be in the link 
command since we are linking statically. What you need to do is figure 
out why your application's makefile doesn't link to the needed libraries.

If you do "make VERBOSE=1" you should see the link command behind "CXXLD 
focus.exe". Try manually adding the missing -l arguments to this command.

The next job is to make this happen automatically. One possibility is 
that your application's build configuration has a problem. Are you using 
cmake? Another is that the cmake files from vtk are missing something.

Please share your results!
