Add more Qt and Python packages and frameworks to the macOS package #64516
Description
Feature description
Goal: make more plugins work on macOS (e.g. those that rely on QtWebEngine for embedded web previews (like qgis2web)).
Observation: It is hard to get some plugins to work with QGIS for macOS. For example, the official QGIS.app doesn’t bundle the QtQuick.framework, so the bundled python/pip can install PyQtWebEngine, but it cannot load because the required Qt frameworks aren’t present.
QtWebEngineWidgets.abi3.so shows hard deps on:
@rpath/QtQuick.framework/...
@rpath/QtQml.framework/...
@rpath/QtQmlModels.framework/...
@rpath/QtWebEngineCore.framework/...
@rpath/QtWebEngineWidgets.framework/
But these are not present.
Suggested improvement
Consider bundling a minimal additional set of Qt/Python frameworks and packages (e.g. QtQuick/QtQml + QtWebEngine) in the official macOS build, so that for example plugins relying on QtWebEngine embedded previews can work without requiring users to rebuild QGIS or modify the app bundle/codesigning.
This would improve plugin compatibility and user experience on macOS.
