title: qt 5.8 sql connection error:QMYSQL driver not loaded on windows 10
body: <p>When i tried to connect to mysql, there is a error:</p>
  
  <pre><code>QSqlDatabase: QMYSQL driver not loaded
  QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
  "Driver not loaded Driver not loaded"
  </code></pre>
  
  <p>So i googled it, and i tried :</p>
  
  <p>1.Copy sqldrivers folders to C:\Qt\Qt5.8.0\5.8\mingw53_32\plugins </p>
  
  <p>2.Copy libmysql.dll to C:\Qt\Qt5.8.0\5.8\mingw53_32\bin </p>
  
  <p>but the error is still there.</p>
  
  <p>Is there anything i am missing?</p>
