Plugins must be shipped with runtime or compiled statically, was: Another problem about c++ demo interface

I added several c++ classes and import libraries to the QT project from ADK. However, after compiling, AmiBroker does not recognize the plugin. Who can provide some ideas?
All necessary functions in plugin interface do exist.Thanks,it frustrated me~

Good Morning.
I've finished another mission last week and I'm sorry to reply now.
For the reasons explained in this article, I went to Microsoft's official website to re-download it. But it didn't improve. I've added a lot of link libraries to the qt demo, and the compiled size reached more than 1 megabyte.
would you provide me with some common unrecognized reasons for data plugin?
thanks.
