SYSTEMΒΆ
New in version 3.25.
Specifies that a target is a system target. This has the following effects:
Entries of
INTERFACE_INCLUDE_DIRECTORIESare treated as system include directories when compiling consumers. Entries ofINTERFACE_SYSTEM_INCLUDE_DIRECTORIESare not affected, and will always be treated as system include directories.
For imported targets, this property defaults to true, which means
that their INTERFACE_INCLUDE_DIRECTORIES are treated
as system directories by default. If their SYSTEM property is false,
then their INTERFACE_INCLUDE_DIRECTORIES 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.
