你好， 我到了生成 exe的 最后一步，但是出现了上面的错误。 可以问下是什么原因吗？谢谢！

另外我没有找到QVTKWidget.dll,所以只把QVTKWidgetPlugin.dll 复制到了 \qt5.12.9\5.12.9\msvc2017_64\plugins\designer 下面。会是这个的原因吗

image 缺少一个Qvtkwidget.dll的依赖

VTK需要重新编译才能得到QVTKWidget.dll, 参考: https://github.com/nightn/CloudViewer/blob/master/doc/compiling-cloudviewer-windows.md#VTK编译
