NO_SYSTEM_FROM_IMPORTEDΒΆ

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.

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