Installing opencv on gorgon

### save this script as install_opencv.sh
### in a directory with more than 8 GB of space, run this script
### this will install to INSTALL_PREFIX
### The implication is that this will not install if you run it 
### from your AFS space (unless you have requested a quota increase)
### One option is to move the script to /scr, run it from there
### This is good for both gorgon and deep machines.
### NOTE: Requires CMake 2.8+
