Ok, found it.

I'd suggest:
relative to CMAKE_INSTALL_PREFIX, i.e. not configurable via the cache anymore.

Advantage: easier handling, and especially under Windows the package can be 
installed easily to arbitrary locations.

This would mean that if CMAKE_INSTALL_PREFIX is e.g. /opt/phonon, the headers 
would always bee in /opt/phonon/include, the libs in /opt/phonon/lib[64], 
share in /opt/phonon/share. (currently you can configure these three locations 
to completely independent locations, which I think is not necessary for a 
library like phonon).

I would suggest to install the buildsystem files not into share/phonon-
buildsystem/, but into share/phonon/buildsystem/.
Then also this generated library thingy file which is currently installed 
directly to CMAKE_INSTALL_PREFIX (I think you don't really mean that) could go 
e.g. into share/phonon/. Or maybe lib/phonon/.

There will be a PhononConfig.cmake file, which will be found by 
find_package(), and it will contain all the information about the installed 
phonon, like e.g. the include dir.
It will be placed in lib/cmake/phonon/.
Alternatively it could also go into lib/phonon/cmake/.

What do you think ?
Objections ?
