INSTALL_PARALLELΒΆ
Added 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.
