[SOLVED] Export all symbols from dlls on windows (including Qt metaobjects)

Issue

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?

Solution

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.
