[vtkusers] Slow linking under Linux

[Katarzyna Wilamowska]

I've built VTK 5.0.3 under Linux  (using Cmake version 2.4 patch 6).   
When I compile my own code using a Cmake generated Makefile, the  
linking process takes a very long time (1-2 minutes for a file that's  
only 50 lines long).
Has anyone else experienced this problem?  What sort of solution  
fixed it? Is it perhaps an incorrect flag setting?
Thank you,
