Which qca-qt5 are you using? It is currently wonky, because developers cannot agree on proper Qt4 vs. Qt5 detection.
Seeing the library is "just" called /usr/lib/libqca.so.2 you are linking against the Qt4 version, which of course does not work at runtime.
Well i had switched from a git version of qca to more stable version. Kget had been working previously so that does explain like you said Kget its not running
