+Error on non-existent dependency in add_dependencies.
+
+CMake 2.8.12 and lower silently ignored non-existent dependencies
+listed in the :command:`add_dependencies` command.
+
+The OLD behavior for this policy is to silently ignore non-existent
+dependencies. The NEW behavior for this policy is to report an error
+if non-existent dependencies are listed in the :command:`add_dependencies`
+command.
+
+This policy was introduced in CMake version 3.0.
+CMake version |release| warns when the policy is not set and uses
+OLD behavior. Use the cmake_policy command to set it to OLD or
+NEW explicitly.
