This just means that you can have multiple versions of CMake on the same 
machine.   You removed the cmake that built your VTK, you need to re-run 
the new cmake on your VTK, and all should be well.

cd old-vtk-build
/usr/local/bin/cmake ../VTK

Assuming /usr/local/bin/cmake is the new cmake, then you should be all set.
