One more brief note on that: If you have already run cmake (or ccmake) from the source directory, make sure you delete the CMakeCache.txt from the source directory before attempting to run cmake or ccmake from the binary directory.  CMake has a funny habit of refusing to let you do an out-of-source build once you have created an in-source-build.  If you have trouble, just delete everything and untar the source again to start fresh.
