# Options:
6+
#
7+
# IOS_PLATFORM = OS (default) or SIMULATOR
8+
# This decides if SDKS will be selected from the iPhoneOS.platform or iPhoneSimulator.platform folders
9+
# OS - the default, used to build for iPhone and iPad physical devices, which have an arm arch.
10+
# SIMULATOR - used to build for the Simulator platforms, which have an x86 arch.
11+
#
12+
# CMAKE_IOS_DEVELOPER_ROOT = automatic(default) or /path/to/platform/Developer folder
13+
# By default this location is automatcially chosen based on the IOS_PLATFORM value above.
14+
# If set manually, it will override the default location and force the user of a particular Developer Platform
15+
#
16+
# CMAKE_IOS_SDK_ROOT = automatic(default) or /path/to/platform/Developer/SDKs/SDK folder
17+
# By default this location is automatcially chosen based on the CMAKE_IOS_DEVELOPER_ROOT value.
18+
# In this case it will always be the most up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path.
19+

23+

24+

25+
