-# This file is based off of the Platform/Darwin.cmake and Platform/UnixPaths.cmake
-# files which are included with CMake 2.8.4
-# It has been altered for iOS development
-
-# Options:
-#
-# IOS_PLATFORM = OS (default) or SIMULATOR
-#   This decides if SDKS will be selected from the iPhoneOS.platform or iPhoneSimulator.platform folders
-#   OS - the default, used to build for iPhone and iPad physical devices, which have an arm arch.
-#   SIMULATOR - used to build for the Simulator platforms, which have an x86_64 arch.
-#
-# IOS_DEVELOPER_ROOT = automatic(default) or /path/to/platform/Developer folder
-#   By default this location is automatcially chosen based on the IOS_PLATFORM value above.
-#   If set manually, it will override the default location and force the user of a particular Developer Platform
-#
-# IOS_SDK_ROOT = automatic(default) or /path/to/platform/Developer/SDKs/SDK folder
-#   By default this location is automatcially chosen based on the IOS_DEVELOPER_ROOT value.
-#   In this case it will always be the most up-to-date SDK found in the IOS_DEVELOPER_ROOT path.
-#   If set manually, this will force the use of a specific SDK version
-
-# Macros:
-#
-# set_xcode_property(TARGET XCODE_PROPERTY XCODE_VALUE)
-#  A convenience macro for setting xcode specific properties on targets
-#  example: set_xcode_property(myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1")
