How do you know it doesn't search elsewhere?

I could add thousand additional paths and put the needed dll in every single one of them, but only the one lies in the qt/plugins-path will be used.
And this is not that good, if I want to use my application on a PC without Qt :/
Apparently you are missing some library that is required by the driver. Run dependency walker on the plugin and see if anything is missing and what is required for it to work.
