CMAKE_UNITY_BUILD
-----------------
-Default value for :prop_tgt:`UNITY_BUILD` of targets.
-
-By default ``CMAKE_UNITY_BUILD`` is ``OFF``.
+Initializes the :prop_tgt:`UNITY_BUILD` target property on targets
+as they are created. Set to ``ON`` to batch compilation of multiple
+sources within each target. This feature is known as "Unity build",
+or "Jumbo build". By default this variable is not set and so does
+not enable unity builds on targets.
