Qt Creator cannot appears custom widgets

Re: Designer plugin only appears in standalone designer
Hi, all
I am using the latest Qt 5.13.0.
Qt Creator: Based on Qt 5.12.3 (MSVC 2017, 32 bit)
Qt Designer(standalone): MSVC 2017, 32-bit
I create a simple custom widget, copy the *.lib and *.dll to the directory "C:\Qt\Qt5.13.0\5.13.0\msvc2017\plugins\designer"(dir1), the plugin appears successfully.
But when I copy the same *.lib and *.dll to "C:\Qt\Qt5.13.0\Tools\QtCreator\bin\plugins\designer"(dir2), the plugin cannot appears in the designer of Qt Creator.
I found two information in the Qt directory:

1. The designer plugin of Qt Creator is "Designer4.dll", I think it's different from the standalone Qt Designer.
2. qaxwidget.dll and qquickwidget.dll, they are different between "dir1" and "dir2".
   So I want to know how to make the custom widget appears in Qt Creator, and what's the compiler version of "Designer4.dll"?

Best regards！

You have to use same Qt version and same compiler as used by QtCreator/Designer for your custom widgets.
That means in your case you have to use Qt 5.12.3 and MSVC 2017, 32 bit
