ExternalProject is really powerful, one of the best additions to CMake
in the last years, IMHO.

See http://gitorious.org/winstng for an example of ExternalProject
which bootstraps, downloads and builds a Wt ( http://webtoolkit.eu )
and all of its dependencies.

It's a tiny shell script (.bat on Windows, bash script on Unix) that
downloads and builds everything from CMake to the PostgreSQL. The only
requirement is a C++ compiler.

winstng still needs some fixes on Mac (where GNU coreutils, etc are
not available) but it works pretty well on Windows and Linux, and on
Mac if you haven't messed too much with Macports/Fink/Homebrew.
