Description

Metatask to migrate to Qt6. Steps are:

Migrate to Qt5.12 as minor version if needed because "old" supported distributions has not yet changed to Qt5.15 minimal.
Migrate to Qt5.15 :
- integrate https://phabricator.kde.org/T10168 / https://invent.kde.org/education/gcompris/-/merge_requests/78
- to be able to use Version-less CMake targets (see https://www.qt.io/blog/versionless-cmake-targets-qt-5.15 and https://doc.qt.io/qt-6/portingguide.html)
- bump android ndk to r22b
Migrate to Qt6.2.x: POC in branch work/poc/qt6. It would be complicated to keep the cohabitation between Qt5 and Qt6 due to qml

https://bugreports.qt.io/browse/QTBUG-103926 : either it's a bug or we need to prefix all our "Qt.Key_*" in javascript files to "QtQuick.Qt.Key_*" (this affects at least balancebox and land_safe)
edit: it is expected from Qt, so we need to update our code. As it is not compatible with Qt5, it needs to be done only in Qt6 branch when we'll port

There seem to be an issue with one image: qrc:/gcompris/src/activities/binary_bulb/BinaryBulb.qml:58:9: QML QQuickImage: Error decoding: qrc:/gcompris/src/activities/digital_electricity/resource/texture01.webp: Unsupported image format (only Qt6 so not a big issue for now)

Edit -> this was due to missing Qt6 images format plugin, it is fixed after installation.
