+IOS_INSTALL_COMBINED
+--------------------
+
+Build a combined (device and simulator) target when installing.
+
+When this property is set to set to false (which is the default) then it will
+either be built with the device SDK or the simulator SDK depending on the SDK
+set. But if this property is set to true then the target will at install time
+also be built for the corresponding SDK and combined into one library.
+
+This feature requires at least Xcode version 6.

+* When building for embedded Apple platforms like iOS CMake learned to build and
+  install combined targets which contain both a device and a simulator build.
+  This behavior can be enabled by setting the :prop_tgt:`IOS_INSTALL_COMBINED`
+  target property.
