This is not entirely true, CPack RPM and DEB may automatically handle
absolute install path.

I don't quite understand what you said.
You may install your include in a **relative** DESTINATION include
then install binaries in a **relative** DESTINATION bin
then you get the appropriate unix separation without requiring
absolute install path?

If ever bin and include do not share the same prefix then you may create
component package and unpack those at appropriate prefix.

By the way using absolute install path on Windows just does not work or
sometimes produces unexpected (and probably unwanted) behavior.
CMake 2.8.8 (or 9 I'm unsure) and up should warn you about that.

May be you could give us some example of use of absolute install path
and your expected behavior so that we can speak on concrete exemple?

Most (if not all) of the time using absolute install paht is NOT necessary
to obtain what you want.
