SYSTEMΒΆ
New in version 3.25.
Specifies that a target is a system target. This has the following effects:
Entries of
INTERFACE_INCLUDE_DIRECTORIES
are treated as system include directories when compiling consumers. Entries ofINTERFACE_SYSTEM_INCLUDE_DIRECTORIES
are not affected, and will always be treated as system include directories.On Apple platforms, If the
FRAMEWORK
target property is true, the frameworks directory is treated as system.
For imported targets, this property defaults to true, which means
that their INTERFACE_INCLUDE_DIRECTORIES
and, if the
FRAMEWORK
target property is true, frameworks directory are
treated as system directories by default. If their SYSTEM
property is
false, then their INTERFACE_INCLUDE_DIRECTORIES
as well as
frameworks will not be treated as system. Use the EXPORT_NO_SYSTEM
property to change how a target's SYSTEM
property is set when it is
installed.
For non-imported targets, this target property is initialized from
the SYSTEM
directory property when the target is created.
