Hm, I don't see this behavior with CMake 2.8.1 on Mac OS X. When reading this I
thought this might be related to http://www.cmake.org/Bug/view.php?id=10048,
but as I can't reproduce it I'm a bit lost. What generator are you using?
As an aside: You should NEVER (as in "verboten") write to the source tree, only
to the binary tree.
