-------
Utility targets may not have link dependencies.
CMake 2.8.12 and lower allowed using utility targets in the left hand side
position of the :command:`target_link_libraries` command. This is an indicator
of a bug in user code.
The ``OLD`` behavior for this policy is to ignore attempts to set the link
libraries of utility targets. The ``NEW`` behavior for this policy is to
report an error if an attempt is made to set the link libraries of a
utility target.
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 :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
