Brad King 482a3bf3f0 Help: Document explicitly that policy OLD behavior is deprecated
The most likely documentation page a project author will read in
response to a policy warning is the page for the policy itself.
Add to every policy documentation page a note explicitly stating
that the OLD behavior is deprecated.  Also mention this in the
cmake_policy() command documentation that explains how to set a
policy to OLD.

-------
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.
