Add resource file (*.qrc) to static library. How?

[bogong]

Hello all!

Trying to add QML files to static library (need to create universal library within QML). All is working when directly adding QML with 'qt_add_qml_module'. Something like this:

qt_add_qml_module(${A_NAME_TARGET}
	URI "Library_v1"
	QML_FILES
		"ATestQML.qml"
)

How to add *.qrc files to library and how to use it in the main project? When adding *.qrc file to the library with 'qt_add_qml_module' return error:

qt_add_qml_module(${A_NAME_TARGET}
	URI "Library_v1"
	RESOURCES
		TestResources.qrc
)

error in the main project:

QQmlApplicationEngine failed to load component
qrc:/qt/qml/Application_v1/Main.qml:12:2: ATestQML is not a type

I don't know anything specific about QML modules, but in general - if you want to load a resource file from a static library, you need explicitly load it by adding the Q_INIT_RESOURCE macro somewhere in your main application target. See the docs: https://doc.qt.io/qt-6/qtresource-qtcore-proxy.html#Q_INIT_RESOURCE

You would use qt_add_resources() for *.qrc files: https://doc.qt.io/qt-6/qt-add-resources.html

However, if your *.qml files are inside a *.qrc then you won't get the full benefits of qt_add_qml_module() (such as optimization via the Qt Quick Compiler: https://www.qt.io/blog/the-numbers-performance-benefits-of-the-new-qt-quick-compiler).

It is better to move all your files out of the *.qrc, and directly into the qt_add_qml_module():

qt_add_qml_module(${A_NAME_TARGET}
	URI Library_v1
	QML_FILES
		ATestQML.qml
		BTestQML.qml
	RESOURCES
