QSqlDatabase: QMYSQL driver not loaded 解决方法

在Linux下用qt连接mysql数据库时，连接不上数据库，报QSqlDatabase: QMYSQL driver not loaded这个错误。

sudo apt-get install libqt4-sql-mysq或者sudo apt-get install libqt5-sql-mysq 安装qt sql驱动

The Ubuntu 14.04 ships with libmysqlclient 18 while the Qt 5.3.1 is built with 16. So the creating of a symlink like above did not solved my issue.
Finally I have downloaded the libmysqlclient 16 from here:
