JOB_POOLS
---------

Ninja only: List of available pools.

A pool is a named integer property and defines the maximum number
of concurrent jobs which can be started by a rule assigned to the pool.
The ``JOB_POOLS`` property is a semicolon-separated list of
pairs using the syntax ``NAME=integer`` (without a space after the equality sign).

For instance:

.. code-block:: cmake

  set_property(GLOBAL PROPERTY JOB_POOLS two_jobs=2 ten_jobs=10)

Defined pools could be used globally by setting
:variable:`CMAKE_JOB_POOL_COMPILE` and :variable:`CMAKE_JOB_POOL_LINK`
or per target by setting the target properties
:prop_tgt:`JOB_POOL_COMPILE` and :prop_tgt:`JOB_POOL_LINK`.
:command:`Custom commands <add_custom_command>` and
:command:`custom targets <add_custom_target>` can specify pools using the
option ``JOB_POOL``.
Using a pool that is not defined by ``JOB_POOLS`` causes
an error by ninja at build time.

If not set, this property uses the value of the :variable:`CMAKE_JOB_POOLS`
variable.

Build targets provided by CMake that are meant for individual interactive
use, such as ``install``, are placed in the ``console`` pool automatically.
