WebView and WebEngine not installed error

Hi,

I try to use WebView or WebEngine in qml on MacOSX with Qt 5.7 and QtCreator and i get this error:

QQmlApplicationEngine failed to load component
qrc:/main.qml:3 module "QtWebView" is not installed

I have WebEngine installed from the MaintenanceTool

I attached a minimal project that reproduce the issue.
Maybe i forget something to make it work.
