Problem with install icons + make install DESTDIR=<foo>

[Laurent Montel]

Hi,
Our cmake script to install icons doesn't allow to install icons with 
different DESTDIR :(
It will be a problem for future when distro will package kde4.0
(we use DESTDIR to create package)

I think that it's necessary to fix it.

CONFIGURE_FILE( /home/lmontel/kde-4.0/kde4/cmake/snapshot/kdebase/pics/crystalsvg/cr48-app-penguin.png /home/lmontel/kde-4.0/kde4/build-cmake-snapshot//share/icons/crystalsvg/48x48/apps/penguin.png 
COPYONLY)
