Wireshark-dev: [Wireshark-dev] QT Plugin produces function not defined error on run time

Hi!
I just started developing a plugin with QT, I tried the example given at https://github.com/wireshark/wireshark/tree/master/plugins/epan/pluginifdemo. Modified Makefile.am and CMakeFiles.txt according to wireshark-2.4.5, but it didn't work. The QT files were not being compiled. So I took the QT files added it to ui/qt directory with some modification in includes. The QT files were now in ui/qt folder and the rest of the plugin was in plugins/pluginifdemo folder. The program successfully compiled. But upon running wireshark it produces error "undefined symbol: pluginifdemo_ui_about". What am I missing here? ==================================
