Ok, invoking cpack directly and overriding on the command line
works, but overriding in the list file does not work.

I downloaded it just two days ago: 2.8.2 on MacOS 10.5 (64 bit OS),
the file name is "cmake-2.8.2-Darwin-universal.dmg"

Overriding the setting of CPACK_PACKAGING_INSTALL_PREFIX either in the list
file, or on the command line, has no effect.  Also if I try to look at
it's default value via the "message" command, it's blank.

Note that the issue of "./usr/" being prepended only happens with PackageMaker.
I have not tried DragNDrop, because that's no good for libraries.
