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. # # # Macros # ------ # # set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE) # # A convenience macro for setting Xcode specific properties on targets. # # Example: # # set_xcode_property(myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1") # # find_host_package (PROGRAM ARGS) # # A macro to find executable programs on the host system, not within the # iOS environment.
