# The minimal ios toolchain file: https://github.com/simdsoft/1kiss/blob/dev/1k/ios.cmake
# version: 4.1.3

# The supported params:
# PLAT: iOS, tvOS, default: iOS
# ARCHS: arm64, x86_64, default: arm64
# DEPLOYMENT_TARGET: default: iOS=11.0/12.0, tvOS=15.0, watchOS=8.0
# SIMULATOR: TRUE, FALSE, UNDEFINED(auto determine by archs)
# ENABLE_BITCODE: FALSE(default)

# !!!Note: iOS simulator, there is no xcode General tab, and we must set
# CMAKE_OSX_SYSROOT properly for simulator, otherwise will lead cmake based
# project detect C/C++ header from device sysroot which is not present in
