Very interesting.
I have the same problem when I need to access MySQL database from Qt application on Windows
There is no MySQL database support ( through plugin dll as it is at Qt ) , no MySQL plugin in LGPL Qt version
Where to get mysqlplugin.dll for database support? Where to get souce codes or dll file for MySQL support.
When no MySQL plugin I've used QT - MYSQL -ODBC bridge on windows to access the database
