Qt app with MySQL works in developing machine but not in deploying one

You can set an override search path for the runtime linker using the LD_LIBRARY_PATH environment variable in your start script:

export LD_LIBRARY_PATH=/your/library/path:$LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/your/library/path:$LD_LIBRARY_PATH

To copy to clipboard, switch view to plain text mode 

If you do that in a shell, ldd will also use it, so you can verify which Qt is picked up for your application.
