Qtvcp in Qtcreator

Hi!
I installed qtvcp and integrated with designer. I made a simple app and it works. I would like to create an application in Qtcreator but I don't have linuxcnc widgets when I edit the ui file. I tried to add files "qtvcp_plugin.py" and "libpyqt5.so". Now i can see the widgets but i can't compile the project - error: qtvcp.widgets.gcode_graphics: No such file or directory (and others widgets).

Debian 11, Linuxcnc 2.9 (i tried also 2.10)..., Qt 5.15.2, QtCreator 4.14.1

What can I do?
 

I've dont used qtdreater and don't know anyone that has.
Why do you wish to use it?
My guess is it is missing a path to the widgets.
