If you are bootstrapping cmake, the same way, i.e. --prefix is supported by 
the configure and bootstrap scripts in the cmake sources.

If you are building cmake with an already installed cmake, set 
CMAKE_INSTALL_PREFIX, e.g. cmake -DCMAKE_INSTALL_PREFIX=/boot/common <dir>

or you can use ccmake, you cmake-gui, or "make edit_cache" if you have already 
a buildtree.
