IMPORTED_NO_SYSTEM

New in version 3.23.

Deprecated since version 3.25: IMPORTED_NO_SYSTEM is deprecated. Please use the following alternatives instead:

• Set SYSTEM to false if you don't want a target's include directories to be treated as system directories when compiling consumers.

• Set EXPORT_NO_SYSTEM to true if you don't want the include directories of the imported target generated by install(EXPORT) and export() commands to be treated as system directories when compiling consumers.

Setting IMPORTED_NO_SYSTEM to true on an imported target specifies that it is not a system target. This has the following effects:

• Entries of INTERFACE_INCLUDE_DIRECTORIES are not treated as system include directories when compiling consumers (regardless of the value of the consumed target's SYSTEM property), as they would be by default. Entries of INTERFACE_SYSTEM_INCLUDE_DIRECTORIES are not affected, and will always be treated as system include directories.

• On Apple platforms, when the target is a framework, it will not be treated as system.

This property can also be enabled on a non-imported target. Doing so does not affect the build system, but does tell the install(EXPORT) and export() commands to enable it on the imported targets they generate.

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.
