[Qt-qml] How to deploy a QML app with WebView on a machine without a Qt installation?

Thanks - this helped a lot!

And you are right, it is picking up the qmldir from the Qt installation dir.

[2180] QDeclarativeImports(file:///D:/temp/demo/qml/webbrowser/webbrowser.qml::importExtension:
loaded "C:/src/qt/qt/imports/QtWebKit/qmldir"

Later it picks up the correct .dll:
[2180] QDeclarativeImportDatabase::importPlugin: "QtWebKit" from
"D:/temp/demo/qmlimports/qmlwebkitplugin.dll"

In this case I had the "qmldir" file is in the qmlimports/ dir.

This begs the question "why" and "how". To me this starts to look like
the path where QML is looking for the qmldir file is being hard coded
at installation time. No? In the case where it doesn't work, QML is
setting the import path to something non-existing (look at the log
below,  first line. It's the same in both traces and this is not what
I would expect).

Or are there still some tricks I can play so that QML importer would
not look into a Qt installation dir?

Here's the complete log with QML import traces when it works:

>From the trace where it does not work, it is not finding the "qmldir" file.

Any ideas from this?
