QMYSQL driver not loaded but available

I am trying to connect my Qt application with MySQL, and am getting the (notorious, it seems) QMSQL driver not loaded but available error. I have done research and read a number of possible solutions for this problem, but it seems as though there are a number of solutions and I am somewhat confused on what avenue to pursue for my particular case.

I am using Qt 5.7.0 and Ubuntu 16.04.

Here is my code to connect to the db:

Code:

db = QSqlDatabase::addDatabase("QMYSQL");
    db.setHostName("host");
    db.setUserName("name");
    db.setPassword("password");
    db.setDatabaseName("dbName");
    bool ok = db.open();

I believe line 2 above is the problem. So my question is essentially, how to I fix the libmysqlclient_r.so.16 => not found error?
