FIrst of all, there are a couple of discussions about using
CPACK_SET_DESTDIR, install prefixes and co in this list which are about same
problems: directory layout depends on generator used.
Next, cmake_install files (which contain install rules) are generated at
cmake time and it may be possible to code some variables there, which then
can be passed through cpack.
