+
+	[cmake] Add iOS build support.
+
+	* builds/cmake/iOS.cmake: New file.  Universal binaries are built
+	with both 32 and 64 bit arm architectures.
+
+	* CMakeLists.txt (IOS_PLATFORM): New variable for running the iOS
+	toolchain.  Possible values are `OS' to build on iOS, or
+	`SIMULATOR' to build on APPLE.

+# 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.
