I finally got it to build, and the executable even works - KPA demo 
database opened successfully on Windows :).


The solution to those "unresolved external symbol"-errors was to RTFM, 
and to follow this practice with kpabase and kpathumbnails:
https://doc.qt.io/qt-6/sharedlibrary.html

I.e. for kpabase adding this at the start of the header file:
#if defined(KPABASE_LIB)
#define KPABASE_EXPORT Q_DECL_EXPORT
#else
#define KPABASE_EXPORT Q_DECL_IMPORT
#endif

and then using it like this in couple of lines in the header:
KPABASE_EXPORT Q_FLAG_NS(VideoBackend)
class KPABASE_EXPORT SettingsData : public QObject ...


And of course, had to add also compile definitions to the CMakeLists.txt 
for those libraries:
target_compile_definitions(kpabase PRIVATE KPABASE_LIB)


Happy now.


Need to experiment still with MinGW, so that it would compile without 
the modifications I did with files needing dirent.h and uninstd.h, but 
that can wait...
