Description
I have one of the 3rd Generation iPad Pros which has the arm64e architecture. When building OF during the linking phase of compliation many of the internal libraries are not compiling. I tried reverting the architecture to arm64 but then was not able to deploy to the application because the architecture does not match the A12 chip on the iPad Pro.
I know these devices were just released a month or so ago - and I'm wondering if all these libraries have to be recompiled in order for OF to work on the latest iPad?

Research direction
Start with the arm64e linker warnings and the referenced archives in libs/boost/lib/ios, libs/FreeImage/lib/ios, and libs/tess2/lib/ios. Check how these libraries are built for iOS and whether arm64e slices are required; done means the project links and deploys successfully on the 3rd Generation iPad Pro.
