* 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.2.6.5

# 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. |
||||
