NO_SYSTEM_FROM_IMPORTED — CMake 3.24.2 Documentation

# NO_SYSTEM_FROM_IMPORTED

Do not treat include directories from the interfaces of consumed Imported Targets as `SYSTEM`.

The contents of the `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. Either way, entries of `INTERFACE_SYSTEM_INCLUDE_DIRECTORIES` are not affected, and will always be treated as `SYSTEM` include directories.

This property is initialized by the value of the `CMAKE_NO_SYSTEM_FROM_IMPORTED` variable if it is set when a target is created.

See the `IMPORTED_NO_SYSTEM` target property to set this behavior on the target providing the include directories rather than consuming them.
