    Default Problem with MySQL drive on mac

    I am working on MySQL database on mac, run program generates the following error.

    QSqlDatabase: QMYSQL driver not loaded
    QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7

    I have MySQL installed on my computer (macOS high Sierra) that has the following driver libmysqlclient.20.dylib. The MySQL path is the following:


    I have executed the following code:

    cd /Users/eduardo/Qt/5.11.1/clang_64/plugins/sqldrivers
    otool -L libqsqlmysql.dylib

    libqsqlmysql.dylib (compatibility version 0.0.0, current version 0.0.0)
    @rpath/QtSql.framework/Versions/5/QtSql (compatibility version 5.11.0, current version 5.11.1)
    @rpath/QtCore.framework/Versions/5/QtCore (compatibility version 5.11.0, current version 5.11.1)
    /System/Library/Frameworks/DiskArbitration.framework/Versions/A/DiskArbitration (compatibility version 1.0.0, current version 1.0.0)
    /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0)
    /usr/local/mysql/lib/libmysqlclient.20.dylib (compatibility version 20.0.0, current version 20.0.0)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 307.5.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.50.2)

    Does anyone know how I can connect to my database?
    I have researched in the net and I have found that it is used, install_name_tool –change ,although I am not sure what it is for. I have tried this but obviously something is wrong.
    install_name_tool – change /usr/local/mysql/lib/libmysqlclient.20.dylib /usr/local/mysql-8.0.15-macos10.14-x86_64/lib/libmysqlclient.20.dylib /Users/eduardo/Qt/5.11.1/clang_64/plugins/sqldrivers/libqsqlmysql.dylib

    Thanks for help.
