install targets mit cmake funktionieren nicht

ich verstehe nicht warum das oben angegebene cmake-file nicht funktioniert. die libraries werden richtig gebaut, aber die targets NICHT installiert. allerdings werden die unten angegebenen FILES richtig installiert. nur die kde-plugins werden überhaupt nicht berücksichtigt.

das ist mein install output:

Install the project...

kennt sich da irgendjemand besser aus als ich? ich fange langsam an cmake zu hassen.
