Hello,everyone 
can you help me? 
I encountered the following problem when I copied and ran the FourPaneViewer code in Qtcreator today. There are so many __imp__xxxx flags and too many errors make me nervous and doubtful: What should I do?
Error:
Environment:
Windows10, QtCreator with Qt6.8.0, vtk9.3.1(which build debug mode)
Changed:
I just separated the vtkResliceCursorCallback class inherited from the vtkCommand class and wrote it into vtkResliceCursorCallback.h and vtkResliceCursorCallback.cpp.this is my demo tree.

I hope to get some help from all the masters passing by. I would like to thank you in advance.
