a guide on connecting to mysql database

hi all i have gone through the internet to try find how to connect to the database but i think there is a library that i need to add to to my simple desktop application, while trying to create a database instance with this line
QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");

this (QSqlDatabase) comes out as undeclared identifier and that from my newbie knowledge i think is because their is lack of an essential library, i have checked how to do it in command prompt but the commands are not recognized, can somebody help me with step guide on how to do this?

Make sure your db driver is built, if its not here is how your build it:

And this is how you use it:

... and make sure your project file includes the following entry:

Code:
