Subject: [PATCH] Add basic CPack support

This allows creating simple compressed binary packages easily,
which is handy on less mainstream platforms which lack
dedicated packages, or such packages are overkill and
impractical (eg: debian).

For the future it is planned to add some support for at least the
CPack RPM and NSIS generators.

The CPack code is based on the Inkscape project[1].
