CMAKE_OSX_DEPLOYMENT_TARGET should define IPHONEOS_DEPLOYMENT_TARGET for iOS
When cross-compiling for iOS (or ios-simulator) we can use CMAKE_OSX_SYSROOT
to select the proper SDK [1][2], and CMAKE_OSX_ARCHITECTURES
to define the proper architecture [3][4], but setting the deployment target with CMAKE_OSX_DEPLOYMENT_TARGET
will fail as it will set the flag -mmacosx-version-min
instead of -miphoneos-version-min
for ios, and -mios-simulator-version-min
for simulators (should set the proper flag based on the sdk type defined by CMAKE_OSX_SYSROOT
)
/usr/bin/xcrun -sdk iphoneos --show-sdk-path
/usr/bin/xcrun -sdk iphonesimulator --show-sdk-path
- ios: arm64;armv7
- simulator: i386;x86_64
It seems to be defining MACOSX_DEPLOYMENT_TARGET
instead of IPHONEOS_DEPLOYMENT_TARGET
