[Interest] What is the right way of creating a static lib that has qml resources with cmake?

[Alexandru Croitor]

Indeed, /wholearchive exists on windows and can be used with the referenced cmake version, but unfortunately:

- ensuring certain symbols are not discarded
- others are (-gc-sections), 
- it works reliably
- for all platforms that qt supports

is more involved.

See QTBUG-97816 , the comments there, and also linked issues and their comments.

At some point we'll have to revisit if it's perhaps more feasible to do now, or limit it to specific platforms and newer cmake versions.
