Баги в qt_add_qml_module?

Всем доброго времени суток.

Пытаюсь написать нормальный cmake скрипт для сборки и деплоя кутэ приложения (пока только под мак).

Входные условия: два таргета, основное приложение — чисто запускалка всей логики. Вся логика в статической либе.

Суть проблемы: некорректно отрабатывает macdeployqt. Тулза не учитывает модули, которые я импортирую в либе. Но стоит прописать эти импорты в любом .qml файле таргета-приложения, как всё резко начинает работать.

Чтобы не быть голословным, вот наброски: https://github.com/dsazonoff/qt-qml-cmake-testbed/tree/main
И соответственно коммит, который показывает проблему: https://github.com/dsazonoff/qt-qml-cmake-testbed/commit/9fb8ebf13a6664a5c4f17f5a4fedf8492a1f499d
Если же import QtQuick.Dialogs сделать внутри таргета приложения, а не статической либы, то всё ок.

Мысли вслух:
— Где-то что-то не так делаю с target_link_libraries и областью видимости (PRIVATE/PUBLIC)
— Я как-то не так юзаю [qt_add_qml_module](https://github.com/dsazonoff/qt-qml-cmake-testbed/commit/4ed7d9fc248966e6c5fa3019fdfdd641c35fd8c7#diff-c2087cfe428fc15a62ae4ba4a7c02fe67e0216a6993335831102ddef095d592d)
— Я что-то ещё не понимаю про импорт и qml модули...

Определённые ограничения:
— Я не рассматриваю Qt ниже версий 6.6, ибо в последних есть много удобных плюшек
— Пока актуален только мак, но оно всё более-менее кросс-платформенно с xxxxdeployqt
— Не надо предлагать в коде дёргать всякие addImportPath — оно должно само отрабатывать (и отрабатывает для приложений, а не либ), но если ошибка в этом — то укажите
— Не хочется прибегать ни к каким костылям при деплое

Собственно я не поленился сделать репо, которое собирает hello world для отладки, возможно кто-то тыкнет меня в ошибку, а то я уже несколько недель мучаюсь.

P.S. по сути это продолжение вот этого

 топика. По поводу деплоя кутэ5 всё печально. Самые легкогуглящиеся решения требуют питон2 и уже морально устарели. На многих проектах используют самописные костыли.

Здравствуйте, SaZ, Вы писали:

Дисклеймер: я сам пока не использую > 5.15.

При создании статической библиотеки ты используешь qt_add_qml_module. В документации явно сказано:

The STATIC QML modules also generate the static QML plugins if NO_PLUGIN is not specified. Targets that import such STATIC QML modules also need to explicitly link to corresponding QML plugins.

Note: When using static linking, it might be necessary to use Q_IMPORT_QML_PLUGIN to ensure that the QML plugin is correctly linked.


Вроде все работает так, как и описано.

Большое спасибо что посмотрели. Увы, не получилось.
ld: warning: ignoring duplicate libraries: 'source/wheel-lib/libwheel.a'
ld: Undefined symbols:
  qt_static_plugin_wheelplugin(), referenced from:
      __GLOBAL__sub_I_main.cpp in main.cpp.o

Если без макроса Q_IMPORT_QML_PLUGIN(wheelplugin) то собирается, но с деплоем та же проблема — не видит импорт диалогов.

Что поменял: 
target_link_libraries(${target_name} PRIVATE
    ${qt_libraries}
    wheel            # <--- !!!!!
    wheelplugin
)


Выхлоп со включенной отладкой:

QQmlApplicationEngine failed to load component
qrc:/qt/qml/com/dsazonoff/testbed/main.qml:18:5: Type Wheel unavailable
qrc:/qt/qml/com/dsazonoff/wheel/Wheel.qml:4:1: module "QtQuick.Dialogs" is not installed


Update:

Нашёл интересный коммент: That's why there's an additional file in the actual app project (main) that does nothing but import all the modules that the library needs.

Два момента, связанные с QML_ELEMENT:

1. Заголовочный файл должен находится в прямой видимости, то есть #include <MyElement.h> должен резолвиться — иначе не соберётся.
2. Если в проекте используются PCH для Qt, то надо явно подключать #include <QQmlEngine> в том файле где объявляете QML_ELEMENT — иначе не будет генерироваться код регистрации типа.

Здравствуйте, SaZ, Вы писали:

У Qt новый пост про QML плагины вышел: Implicit Imports vs. QML Modules in Qt 6

Для себя сделал вывод, что переходить с 5.15 все еще рано... (при этом у нас плагины определены с помощью CMake).
