This is wrong. There's a misconception that you can't statically link your app when using the open-source LGPL version of Qt. From my reading of the LGPL license this doesn't appear to be the case[1]. The LGPL allows you to statically link your app as long as you provide the object files and allow users to relink your app with a different version of Qt.
replyI've observed many people spreading this misinformation about only being able to dynamically link with the LGPL version of Qt. Please stop this.

Yes, that is true, but in practice nobody has ever done that. And the material complexity of offering that mode is higher than just dynamically linking the library.
replyAlso, modern compilers make this method much harder to use. It is much harder to stably relink object files like that than to just use the normal dynamic link method.
