Description

When building a simple project using Qt Quick for the iOS-simulator I get a linker warning saying "ignoring duplicate libraries".

The command line contains lots of duplicate frameworks but the libraries it complains about are contained in the generated "plugins.list.d" file.

The following project reproduces this behavior:

test.qbs

CppApplication {
	name: "TestApp"
	Depends {
		name: "Qt.quickcontrols2"
	}
	files: [
		"test.cpp",
		"test.qml"
	]
}

test.qml

import QtQuick.Controls

ApplicationWindow {}

test.cpp

int main(){}

This is the output I get when building the above with a profile created with "setup-qt" for Qt 6.6.3 whose parent profile is the default created x86_64 iOS simulator profile:

All in all I could find three separate locations where static libraries are listed which might conflict with each other:

The staticLibs property in the generated quickcontrols2 module
A group in said module containing the actual file of the static lib tagged as "staticlibrary" and using "filesAreTargets: true"
The "plugins.list" file which is generated in qml.qbs and contains many duplicate entries
