+Third Parties
+=============
+
+To build CMake, some third parties are needed. Under ``Utilities``
+directory, are versions of these third parties which can be used as an
+alternate to the ones provided by the system.
+
+To enable the selection of the third parties between the system and CMake ones,
+in CMake sources, third parties headers must be prefixed by ``cm3p/``
+(for example: ``<cm3p/json/reader.h>``). These wrappers are located under
+``Utilities/cm3p`` directory.
