The Qt Mysql plugin should be placed in a directory "sqldrivers" that lives next to the main project executable. This is the app-specific default location searched for SQL plugins. The Mysql runtime library, which is not part of Qt, can be placed anywhere the standard Windows DLL search would look when it loads the plugin dll (on a dev machine this is often on the %PATH). For deployment it is usually most convenient to put it in the "sqldrivers" directory too.

If you do not have a full Mysql install to work from the Mysql Connector for C should contain the run time library:
