# Options:
#
# IOS_PLATFORM = OS (default)
# This needs to be OS as the simulator cannot use the required GLES2.0 environment.
# OS - the default, used to build for iPhone and iPad physical devices, which have an arm arch.
#
# CMAKE_IOS_SDK_ROOT = automatic(default) or /path/to/platform/Developer/SDKs/SDK folder
# By default this location is automatcially chosen based on the CMAKE_IOS_DEVELOPER_ROOT value.
# In this case it will always be the most up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path.
# If set manually, this will force the use of a specific SDK version
