To deploy qt application with plugins you should also add plugins in same folder as application. How to deploy qt applications with plugins

You should also add platform folder near application to be able to deploy your application on computers where qt isn't available.

It's on Linux but same applies in windows. You can only add sqldrivers in plugins folder.

qt.conf file contaians:

[Paths]
Plugins=plugins

Also run Dependency Walker to find all dependent libraries.
