# INSTALL_PARALLEL

New in version 3.30.

Enables parallel installation option for the Ninja generator.

When this property is `ON`, `install/local` targets have the console pool disabled, allowing them to run concurrently.

This property also provides the target `install/parallel`, which has an explicit dependency on the `install/local` target for each subdirectory, recursing down the project.

Setting this property has no affect on the behavior of `cmake --install`. The install must be invoked by building the `install/parallel` target directly.

Calls to `install(CODE)` or `install(SCRIPT)` might depend on actions performed by an earlier `install()` command in a different directory such as files installed or variable settings. If the project has such order-dependent installation logic, parallel installation should be not be enabled, in order to prevent possible race conditions.
