6 Specifies that a target is a ``SYSTEM`` library. This has the following
9 * Entries of :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` are treated as
10 ``SYSTEM`` include directories when compiling consumers.
11 Entries of :prop_tgt:`INTERFACE_SYSTEM_INCLUDE_DIRECTORIES` are not
12 affected, and will always be treated as ``SYSTEM`` include directories.
14 For imported targets, this property defaults to true, which means
15 that their :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` are treated
16 as ``SYSTEM`` by default. If their ``SYSTEM`` property is false,
17 then their :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` will not be
18 treated as ``SYSTEM``, regardless of the value of the
19 :prop_tgt:`IMPORTED_NO_SYSTEM` property.
21 This target property is initialized from the :prop_dir:`SYSTEM`
22 directory property when the target is created.
