# Configure an SDK
#
# Usage:
# configure_sdk_darwin(
# prefix # Prefix to use for SDK variables (e.g., OSX)
# name # Display name for this SDK
# deployment_version # Deployment version
# xcrun_name # SDK name to use with xcrun
# version_min_name # The name used in the -mOS-version-min flag
# triple_name # The name used in Swift's -triple
# architectures # A list of architectures this SDK supports
# )
#
# Sadly there are three OS naming conventions.
# xcrun SDK name: macosx iphoneos iphonesimulator (+ version)
# -mOS-version-min: macosx ios ios-simulator
# swift -triple: macosx ios ios
#
# This macro attempts to configure a given SDK. When successful, it
# defines a number of variables:
#
# SWIFT_SDK_${prefix}_NAME Display name for the SDK
# SWIFT_SDK_${prefix}_VERSION SDK version number (e.g., 10.9, 7.0)
# SWIFT_SDK_${prefix}_BUILD_NUMBER SDK build number (e.g., 14A389a)
# SWIFT_SDK_${prefix}_DEPLOYMENT_VERSION Deployment version (e.g., 10.9, 7.0)
# SWIFT_SDK_${prefix}_LIB_SUBDIR Library subdir for this SDK
# SWIFT_SDK_${prefix}_VERSION_MIN_NAME Version min name for this SDK
# SWIFT_SDK_${prefix}_TRIPLE_NAME Triple name for this SDK
# SWIFT_SDK_${prefix}_ARCHITECTURES Architectures (as a list)
# SWIFT_SDK_${prefix}_ARCH_${ARCH}_TRIPLE Triple name
