Our application needs a universal build of both the leptonic and tesseract libraries. After trying for days to try and coerce the build tools and methods to cough up a universal (arm64/x86_64) binary, I gave up and built both libraries on an M1 Mac mini and then again on an Intel iMac. after that I copied the x86_64 libs to the M1 and used lipo to manually combine them. I build static libs to link with our document management app because I don't want to create complicated installers that have to worry about checking for and installing dynamic libraries in addition to simply dragging the signed and notarized app to the Applications folder. In any case, building on two different macs that used the two different CPUs I need to support and then combining them was the only way I was able to get this done.
