Use of QtWebView when it is installed without all of it's dependent Qt add-on libraries installed results in an app that fails to run properly, with just the message:
No WebView plug-in found!

Enabling plugin debugging with environment variable QT_DEBUG_PLUGINS set to 1 does not provide any further information - just that the webview plugin dll failed to load. This is a common occurrence on Windows - where dependent libraries are hard to diagnose.

Using Windows procmon tool, I was able to determine that I was missing Qt6WebChanneld.dll, and Qt6Positioningd.dll. I was aware that WebView required WebEngine, but I was unaware that it required Positioning and WebChannel.

I expect customers may run into this as well - and it would lead to a bad experience.
Can there be a mechanism to automatically select dependent components in the installer?
Playing around with the installer, it seems like this functionality (relationships between components, and enforcing that dependent components are installed)
