+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 :prop_gbl:`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`.

+JOB_POOL_COMPILE
+----------------
+
+Ninja only: Pool used for compiling.

+The number of parallel compile processes could be limited by defining

+
+For instance:
+
+.. code-block:: cmake
