Please try again with kdesrc-build from current master. I just pushed a patch (mentioned by Michael before) about not moving up the /usr directory in multiple environment variables including CMAKE_PREFIX_PATH, what might have overwritten your manual setting.
Regarding your CMakeCache.txt: /usr/local is the default install location set by cmake because you only set the source location in your cmake call. I don't know more about the other values.
