[CMake] Multiple Versions of CMake

[Sara Rolfe]

Hello,

I have been using CMake on a compute cluster with 64-bit nodes running  
RHEL 5.7.  CMake was not installed on the nodes so I built version  
2.8.4 in my home directory. Recently the cluster nodes were upgraded  
from RHEL 5.7 to RHEL 6.2, which has version 2.6 of CMake installed.   
Now I am getting the following error:

CMake Error at /homes/grail/smrolfe/ITK/bin/ITK-3-20-x86_64/ 
ITKBuildSettings.cmake:10 (message):
   This ITK was built by CMake 2.8.4, but this is CMake 2.6.4.  Please  
upgrade
   CMake to a more recent version.

I would like to change the path to Cmake since I don't have permission  
to upgrade the software on the nodes and would like to continue using  
my own build.  I'd appreciate any pointers.

Thanks,
Sara
