See this recent bug report for some advice in the notes: http://public.kitware.com/Bug/view.php?id=12340 And this old email on the list that contains basically the same advice: http://www.cmake.org/pipermail/cmake/2007-August/015814.html You can also search for CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT -- you can use that value near the top of your top-level CMakeLists.txt file to force-initialize CMAKE_INSTALL_PREFIX to your own default value if you want to.
