IMPORTED_NO_SYSTEM — CMake 3.24.2 Documentation

# IMPORTED_NO_SYSTEM

New in version 3.23.

Specifies that an Imported Target is not a `SYSTEM` library. This has the following effects:

- Entries of `INTERFACE_INCLUDE_DIRECTORIES` are not treated as `SYSTEM` include directories when compiling consumers, as they would be by default. Entries of `INTERFACE_SYSTEM_INCLUDE_DIRECTORIES` are not affected, and will always be treated as `SYSTEM` include directories.

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 providing them.
