Export all symbols from dlls on windows (including Qt metaobjects)
问题
我正在使用Qt 6.5和CMake，我正在寻找一种方法来导出我的dll中的所有符号，而无需手动添加宏。我知道CMake中有WINDOWS_EXPORT_ALL_SYMBOLS，但似乎它不会导出元对象（metaobjects），因此导致链接失败的错误。是否有一种解决方案，可以同时链接Qt的元对象？
英文:
I am using Qt 6.5 and cmake and I am looking for a way to export all symbols from my dlls, without needing to manually add macros to them. I am aware that there is WINDOWS_EXPORT_ALL_SYMBOLS for cmake, but this doesn't seem to export metaobjects, thus giving me errors that tell me that linking those failed.
Is there a solution to this that also links the Qt metaobjects?

这与导出无关。您需要将生成的 moc_<filename>.cpp 包含在您的 <filename>.cpp 中，或者至少作为编译的一部分。确保 CMAKE_AUTOMOC 为 true/on。

This has nothing to do with exports. You need to have the generated moc_<filename>.cpp included in your <filename>.cpp or at least be part of the compilation. Be sure that CMAKE_AUTOMOC is true/on.

我注意到cmake文档提到WINDOWS_EXPORT_ALL_SYMBOLS选项不会自动导出全局和静态符号。这解释了为什么只有静态元对象没有正确导出。
英文:
I have noticed that the cmake documentation mentions that global and static symbols are not exported automatically with the WINDOWS_EXPORT_ALL_SYMBOLS option. This explains why only the static meta objects are not exported correctly.
