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. 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.
