Brad King aab11bcab4 Help: Change version 3.0.0 -> 3.0 in policy docs
Starting with 3.0 we will use only two components for the feature level,
and policies are only ever introduced with a bump to the feature level
version.

CMP0038
-------
Targets may not link directly to themselves.
CMake 2.8.12 and lower allowed a build target to link to itself directly with
a :command:`target_link_libraries` call. This is an indicator of a bug in
user code.
The OLD behavior for this policy is to ignore targets which list themselves
in their own link implementation. The NEW behavior for this policy is to
report an error if a target attempts to link to itself.
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.
