.. versionadded:: 3.25 | |
This directory property is used to initialize the :prop_tgt:`SYSTEM` | |
target property for non-imported targets created in that directory. | |
It is set to true by :command:`add_subdirectory` and | |
:command:`FetchContent_Declare` when the ``SYSTEM`` option is given | |
as an argument to those commands. |
