XCODE_EMIT_EFFECTIVE_PLATFORM_NAME ---------------------------------- Control emission of ``EFFECTIVE_PLATFORM_NAME`` by the :generator:`Xcode` generator. It is required for building the same target with multiple SDKs. A common use case is the parallel use of ``iphoneos`` and ``iphonesimulator`` SDKs. Three different states possible that control when the :generator:`Xcode` generator emits the ``EFFECTIVE_PLATFORM_NAME`` variable: - If set to ``ON`` it will always be emitted - If set to ``OFF`` it will never be emitted - If unset (the default) it will only be emitted when the project was configured for an embedded Xcode SDK like iOS, tvOS, watchOS or any of the simulators. .. note:: When this behavior is enable for generated Xcode projects, the ``EFFECTIVE_PLATFORM_NAME`` variable will leak into :manual:`Generator expressions <cmake-generator-expressions(7)>` like ``TARGET_FILE`` and will render those mostly unusable.
