Libjpeg conflict while building qt

Hi,
I think the easiest would be to remove the development package of the version you do not want to use. It will avoid its detection.

Something is not clear what exactly depends on libjpeg-turbo-dev ?

Sorry, it just realized I misread your issue.
You built Qt successfully but have a problem with your application.
Are you loading a specific file that triggers this error or does it happen for all jpeg files ?

@SGaist Just camera and opencv however the same code runs well without problems on a Raspberry Pi with Qt 5.11.3

libjpeg.so is likely a symbolic link to libjpeg.so.8

How are you loading your image in your application ?
