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 cmake_policy command to set it to OLD or NEW explicitly.
