Summary:                    incremental build dependency problem toggling
VTK_USE_64BIT_IDS
Description: 
Repro:
- build VTK 5.10rc4 with BUILD_TESTING=1
- toggle VTK_USE_64BIT_IDS from its default
- don't 'clean'
- rebuild

Results:
- link errors:

VTK has an incremental build dependency problem. When you build and then change
the setting of VTK_USE_64BIT_IDS, and rebuild, Utilities/LSDyna sees the one
definition of vtkIdType (64bit), and the rest of the build sees the other
(32bit) (or vice versa).

Doing a 'make clean' and then a 'make' is a workaround.

A proper bug fix is to make CMake aware that changing this flag requires a
complete rebuild (like compiler flags do).
