+# XCODE_VERSION: Version number (not including Build version) of Xcode detected.
+# SDK_VERSION: Version of SDK being used.
+# CMAKE_OSX_ARCHITECTURES: Architectures being compiled for (generated from PLATFORM).
+#
+# This toolchain defines the following macros for use externally:
+#
+# set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE XCODE_VARIANT)
+#   A convenience macro for setting xcode specific properties on targets.
+#   Available variants are: All, Release, RelWithDebInfo, Debug, MinSizeRel
+#   example: set_xcode_property (myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1" "all").

+# find_host_package (PROGRAM ARGS)
+#   A macro used to find executable programs on the host system, not within the
