If you are Ubuntu linux OS, you can install library:

mic@ubt: ~$ apt-cache search libqt4-sql-mysql
libqt4-sql-mysql - Qt 4 MySQL database driver

mic@ubt: ~$ sudo apt-get install libqt4-sql-mysql

Well, for Qt5 you need install MySQL, using the next command on the terminal, you resolve the problem:

sudo apt-get install libqt5sql5-mysql
