| Error on non-existent target in get_target_property. |
| |
| In CMake 2.8.12 and lower, the :command:`get_target_property` command accepted |
| a non-existent target argument without issuing any error or warning. The |
| result variable is set to a ``-NOTFOUND`` value. |
| |
| The ``OLD`` behavior for this policy is to issue no warning and set the result |
| variable to a ``-NOTFOUND`` value. The ``NEW`` behavior |
| for this policy is to issue a ``FATAL_ERROR`` if the command is called with a |
| non-existent 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. |
