I found a very good site that might just have the description and the links to all the CMS on the internet.
Probably they are not all, but they are sooooo many.
Here is the address: http://cmsmatrix.org/
Some of them costs, though.
P.S. That's if you don't know much programming, php etc. and you're searching for a aesy/fast sollution to build a site.
