#   -D CMAKE_TOOLCHAIN_FILE=...     <- this file defines the iOS toolchain used for iOS build
#   -D IOS_PLATFORM=OS64            <- OpenCV does not support 32 bit architectures
#   -D IOS_ARCH=arm64               <- OpenCV does not support arm64e, try recompile OpenCV if required
#   -D IOS_DEPLOYMENT_TARGET=12.0   <- for some C++17 features
#   -D ENABLE_BITCODE=0             <- ceres-solver does not support bitcode generation
#   -D ENABLE_ARC=1                 <- required for Objective-C code
