[Interest] OpenCV + Qt iOS: Wrong JPEG library version: library is 62, caller expects 80

[Mike Krus]

mine, for similar issues using GDAL, was to build everything from source, zlib, png, jpeg, tiff, gdal, qt
(making sure you select external jpeg/png for the later).
It’s a pain (and super time consuming) but all due to static linking.
