| SYSTEM |
| ------ |
| |
| .. versionadded:: 3.25 |
| |
| Specifies that a target is a ``SYSTEM`` library. This has the following effects: |
| |
| * Entries of :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` are treated as ``SYSTEM`` |
| include directories when compiling consumers. |
| Entries of :prop_tgt:`INTERFACE_SYSTEM_INCLUDE_DIRECTORIES` are not affected, |
| and will always be treated as ``SYSTEM`` include directories. |
| |
| For imported targets, this property has a default value `ON`, which means that their |
| `INTERFACE_INCLUDE_DIRECTORIES` are treated as ``SYSTEM`` by default. If their |
| `SYSTEM` property is `OFF`, then their `INTERFACE_INCLUDE_DIRECTORIES` will not be |
| treated as ``SYSTEM``, regardless of the value of `IMPORTED_NO_SYSTEM` property. |
