When displaying an image using OpenCV, the following two lines are output to the terminal.

init done
opengl support available

Is there a way to suppress these outputs? These messages are kind of annoying.

That is because the interface is actually flawed. If you would really want to see it disappear in Release build, you should build your project with an extra parameter

Also you can completly disable QDebug with QT_NO_DEBUG_OUTPUT define if you're concerned about performance lost with qDebug present within code.

But some way or the other it should be possible to add this parameter through CMAKE in the Release build. Will take a look at it later this week.
