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

Ulf,
In my latest try I give it a shot to the NO_PLUGIN approach and removed the qt_add_library line. I have also not set qml files with qt_add_resources
qt_add_qml_module(shared STATIC
URI shared
VERSION 1.0
QML_FILES ${SHARED_QML_FILES}
SOURCES ${SHARED_SOURCE_FILES}
NO_PLUGIN
#NO_LINT
#NO_CACHEGEN
)
#set_source_files_properties(<qml files> PROPERTIES BASE <base>)
qt_add_resources(shared "shared_fonts" PREFIX "/" BASE resources FILES ${FONT_FILES})
qt_add_resources(shared "shared_icons" PREFIX "/" BASE resources FILES ${ICON_FILES})
qt_add_resources(shared "shared_js" PREFIX "/" BASE resources FILES ${JS_FILES})
qt_add_resources(shared "shared_json" PREFIX "/" BASE resources FILES ${JSON_FILES})
qt_add_resources(shared "shared_svg" PREFIX "/" BASE resources FILES ${SVG_FILES})
But in the end, the only file that contains qInitResources is: libshared.dylib
But I want it to be libshared.a
What am I missing?
Thanks!
Best,
Nuno
