[Qt-creator] Code model could not parse, but compiled, iOS Framework

Excellent.

It is not listed.

Yes.

Yes.

I wonder how exactly I need to specify it.  https://doc.qt.io/qt-5/qmake-platform-notes.html#using-frameworks says:
LIBS += -F/path/to/framework/directory/ 
but is that the opencv2.framework directory, or the ios directory (see below)

I've tried variations of:
LIBS += -F$$PWD/ios -framework opencv2

Where project is :
project/
project/project.pro
project/main.cpp
project/ios/Info.plist
project/ios/opencv2.framework/
project/ios/opencv2.framework/Headers/...
project/ios/opencv2.framework/Versions/...
project/ios/opencv2.framework/...

Many thanks!
