#
# This file is derived from the files `Platform/Darwin.cmake' and
# `Platform/UnixPaths.cmake', which are part of CMake 2.8.4.  It has been
# altered for iOS development.


# Options
# -------
#
#   IOS_PLATFORM = OS | SIMULATOR
#
#     This decides whether SDKS are 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 architecture.
#     SIMULATOR - used to build for the Simulator platforms, which have an
#       x86 architecture.
#
#   CMAKE_IOS_DEVELOPER_ROOT = /path/to/platform/Developer folder
#
#     By default, this location is automatically chosen based on the
#     IOS_PLATFORM value above.  If you manually set this variable, it
#     overrides the default location and forces the use of a particular
#     Developer Platform.
#
#   CMAKE_IOS_SDK_ROOT = /path/to/platform/Developer/SDKs/SDK folder
#
#     By default, this location is automatically chosen based on the
#     CMAKE_IOS_DEVELOPER_ROOT value.  In this case it is always the most
#     up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path.  If you
#     manually set this variable, it forces 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")
#
#   find_host_package (PROGRAM ARGS)
#
#     A macro to find executable programs on the host system, not within the
#     iOS environment.  Thanks to the `android-cmake' project for providing
#     the command.
