Take a look at this post for Qt5, there's also a seperate set of instructions for Qt4 (although somewhat similar).

Qt - How to get|compile Mysql driver

1. Download a version of MySQL
2. Download Qt source
3. Build the MySQL plugin for Qt
4. Copy the DLL from the MySQL install folder to a Qt folder (see link above)
5. Copy the DLL you built for the Qt MySQL plugin to a Qt folder

And obviously, when you distribute you'll need to remember to package those DLLs together (always check dependency walker)
