Try to look at ExternalProject module
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#module:ExternalProject
and page 10 of 
http://www.kitware.com/products/archive/kitware_quarterly1009.pdf

I have used it (with some mods): it allow to automate download 
pactch,build and install)
Anyway, curl have recently included a CMakeLists in its distribution. I 
have used it even if had to apply some patches.
I am trying to collect some cmake build recipes for some libraries I need.
If you are interested, grab the stuff at
bzr branch http://3d.cineca.it/storage/bazaar_repo/CmakeDeps/lib
