Nothing is ever stored in the source tree.  All your settings are in the 
top level of the build tree in a file called CMakeCache.txt.  A future 
release of CMake will have a feature to print out the list of all your 
changes so that you can use them to initialize another tree, but 
currently this feature is under development.

For now you can manually copy the changed settings out of the cache file 
and put them in a file with the same name in the new build tree using a 
text editor.
