You probably need to google "centos cgal" and then add an appropriate 
repository to yum. I forget the exact way to do that.

Yes, yum is the CentOS equivalent to apt-get. They both work in similar 
ways. There were some good yum howto or tutorials that I learned from 
when I needed to use it that I found via google.
