Can't compile with plugin I created

[KbTeam]

Hello,

I followed the instructions to build the WorldTimeClock Plugin (https://doc.qt.io/qt-6/qtdesigner-worldtimeclockplugin-example.html) to have that Element available in my Toolbox afterwards. So far this works and in my main project I can see and drag&drop it onto the GUI. But when compiling I get an error that "worldtimeclock.h" does not exist:

I made a simple sample to demonstrate the problem here, you can download the zip file: https://daten.xyz/f/fbe25dcd55014ad18324/

What is it that I am missing?

Your project is missing worldtimeclock.cpp and worldtimeclock.h

but why do I need to put them in when I compiled the plugin with Export and can clearly see and use the plugin out of the Widgets toolbox?

Just because you create a plugin for the Qt Designer / QtCreator doesn't mean you need the sources (or the library) with the plugins widget.
