INSTALL_PARALLELΒΆ
Added in version 3.30.
Enables parallel installation option for a project. The install code for each
subdirectory added with add_subdirectory can run independently.
When using the Ninja generator, setting this property to ON, causes
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.
Added in version 3.31.
When this property is
ON,cmake --installcan be given the-j <jobs>or--parallel <jobs>option to specify a maximum number of jobs. TheCMAKE_INSTALL_PARALLEL_LEVELenvironment variable specifies a default parallel level if this option is not provided.
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.
