+XCTEST
+------
+
+This target is a XCTest CFBundle on the Mac.
+
+This property will usually get set via the ``add_xctest`` macro in
+:module:`XCTestUtilities` module.
+
+If a module library target has this property set to true it will be
+built as a CFBundle when built on the mac.  It will have the directory
+structure required for a CFBundle.
+
+This property depends on :prop_tgt:`BUNDLE` to be effective.

+Xcode XCTest Support
+--------------------
+
+* CMake gained the abiltity to create XCTest bundles to test
+  Frameworks and App Bundles within Xcode. The :module:`XCTestUtilities`
+  module provides convenience functions to handle :prop_tgt:`XCTEST` bundles.
