P1: Critical Description
(used the dev branch) Run qt-cmake-private and ninja for the robotarm example. Then try running RobotArmApp.exe.
It fails with:
QQmlApplicationEngine failed to load component qrc:Main/main.qml:10:1: Type App unavailable qrc:/content/App.qml:17:5: Type MainScreen unavailable qrc:/content/MainScreen.ui.qml:10:1: Cannot load library C:\work\qtquick3d_rel_cmake\examples\quick3d\robotarm\Backend\backendplugin.dll: The specified module could not be found.
In addition, though this is not fatal, there are a bunch of CMake warnings:
