Don't know but I would guess for a feature.
I think
CPACK_PACKAGE_INSTALL_DIRECTORY may not be used as you think
by the TGZ generator. I know that we use it on the NSIS (Windows) generator
and this is the install path the tool suggest when you run the installer.

Nevertheless, it's usually a bad idea to build a tar with absolute path name
because you may not be able to untar at this exact ABSOLUTE location.
GNU tar on linux will not even allow it :
>>
 tar zcvf tt.tgz /tmp/mydir
tar: Retrait de « / » de tête des noms des membres
>>
(sorry my Linux is french localized)

Moreover I think that if you want to install your tar.gz in /usr/local
you may do

cd /usr/local
tar --strip-components 1 zxvf you_archive.tgz

the strip components (may be GNU tar only option though)
will remove the top level folder
and you'll get what you want (I think).
