This is a KDE plugin, not a Qt plugin. So I think it belongs where KDE goes. 
That currently the only way to get a working backend in Phonon requires the 
KDE platform plugin is ok, as Qt 4.3 does not ship with Phonon yet. So if you 
want a Qt-only app to use Phonon you need to configure it correctly to use 
KDE (i.e. setting the plugin path env var).

Qt plugins shipped with KDE need to be installed to 
${PLUGIN_INSTALL_DIR}/plugins. Normally another directory follows for 
namespacing.

The Phonon KDE platfrom plugin is installed like this:
install(TARGETS kde DESTINATION ${PLUGIN_INSTALL_DIR}/plugins/phonon_platform)

This path is automatically added to the Qt library paths by 
KApplication::init. So all KDE apps will have it.
