# It has been altered for tvOS development
|
|
|
|
# Updated to XCode 7.x July 2016, Epic Games
|
|
|
|
# Options:
|
|
#
|
|
# TVOS_PLATFORM = OS (default) or SIMULATOR or SIMULATOR64
|
|
# This decides if SDKS will be selected from the TVOS.platform or appleTVSimulator.platform folders
|
|
# OS - the default, used to build for AppleTV physical devices, which have an arm arch.
|
|
# SIMULATOR - used to build for the Simulator platforms, which have an x86 arch.
|
|
#
|
|
# CMAKE_TVOS_DEVELOPER_ROOT = automatic(default) or /path/to/platform/Developer folder
|
|
# By default this location is automatcially chosen based on the TVOS_PLATFORM value above.
|
|
# If set manually, it will override the default location and force the user of a particular Developer Platform
|
|
#
|
|
# CMAKE_TVOS_SDK_ROOT = automatic(default) or /path/to/platform/Developer/SDKs/SDK folder
|
|
# By default this location is automatcially chosen based on the CMAKE_TVOS_DEVELOPER_ROOT value.
|
|
# In this case it will always be the most up-to-date SDK found in the CMAKE_TVOS_DEVELOPER_ROOT path.
|
|
# If set manually, this will force 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 (mytvoslib TVOS_DEPLOYMENT_TARGET "3.1")
|

#
|
|
