NO_SYSTEM_FROM_IMPORTED ----------------------- Do not treat include directories from the interfaces of consumed :ref:`imported targets` as ``SYSTEM``. The contents of the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` target property of imported targets are treated as ``SYSTEM`` includes by default. If this property is enabled on a target, compilation of sources in that target will not treat the contents of the ``INTERFACE_INCLUDE_DIRECTORIES`` of consumed imported targets as system includes. This property is initialized by the value of the :variable:`CMAKE_NO_SYSTEM_FROM_IMPORTED` variable if it is set when a target is created.
