JOB_POOL_LINK

The number of parallel link processes could be limited by defining pools with the global JOB_POOLS property and then specifing here the pool name.

For instance:

set_property(TARGET myexe PROPERTY JOB_POOL_LINK two_jobs)

This property is initialized by the value of CMAKE_JOB_POOL_LINK.
