Shiboken2 qobject.h:46:10:致命:找不到'QtCore/qobjectdefs.h‘文件

Question

我正在尝试使用Shiboken2为Qt C++类创建一个Python绑定。据我所知，还没有关于如何做到这一点的官方示例( Qt博客上唯一的示例涉及泛型C++类https://www.qt.io/blog/2018/05/31/write-python-bindings)。所以我转而关注这篇博文：https://blog.basyskom.com/2019/using-shiboken2-to-create-python-bindings-for-a-qt-library/

这个示例可以在Linux上运行，但Shiboken2无法在Mac上构建，并出现错误qobject.h:46:10: fatal: 'QtCore/qobjectdefs.h' file not found。

这是所发生情况的日志：
