+# This file is derived from the files `Platform/Darwin.cmake' and

+
+
+# 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.
