EXPORT_NO_SYSTEMΒΆ
New in version 3.25.
This property affects the behavior of the install(EXPORT) and
export() commands when they install or export the target respectively.
When EXPORT_NO_SYSTEM is set to true, those commands generate an imported
target with SYSTEM property set to false.
See the NO_SYSTEM_FROM_IMPORTED target property to set this
behavior on the target consuming the include directories rather than the
one providing them.
