Help: Update docs for failure result of get_target_property

Browse Source 
If `get_target_property` fails to find a value for a non-inherited
property, it appends `-NOTFOUND` to the var name and sets that as the
result, rather than setting the value of the var to `NOTFOUND`.

.. code-block:: cmake
get_target_property(VAR target property)
get_target_property(<VAR> target property)
Get a property from a target. The value of the property is stored in
the variable ``VAR``. If the target property is not found, the behavior
the variable ``<VAR>``. If the target property is not found, the behavior
depends on whether it has been defined to be an ``INHERITED`` property
or not (see :command:`define_property`). Non-inherited properties will
set ``VAR`` to ``NOTFOUND``, whereas inherited properties will search the
relevant parent scope as described for the :command:`define_property`
command and if still unable to find the property, ``VAR`` will be set to
set ``<VAR>`` to ``<VAR>-NOTFOUND``, whereas inherited properties will search
the relevant parent scope as described for the :command:`define_property`
command and if still unable to find the property, ``<VAR>`` will be set to
an empty string.
Use :command:`set_target_properties` to set target property values.
