Ah, yeah.
That actually is meant to be installed to CMAKE_INSTALL_PREFIX.

It is only meant for internal usage to conduct ABI checks before
release, by getting one version of Phonon, install it to /tmp/4.4.4/
or somesuch, get another version and install it to /tmp/4.4.57/ and
then run the abi checker on those two. Consequently the less nested
the descriptor file is the better + as it is not actually meant for
deployment it does not matter where it gets installed to anyway. The
only reason it actually can be installed at all is to conveniently
switch between branches in one git clone and retain a once created
build and descriptor (i.e. by installing a build to some directory for
ABI check later on).
