6:module:`FindBoost` reports ``Boost_VERSION`` in ``x.y.z`` format.
7
8In CMake 3.14 and below the module would report the Boost version
9number as specified in the preprocessor definition ``BOOST_VERSION`` in
10the ``boost/version.hpp`` file. In CMake 3.15 and later it is preferred
11that the reported version number matches the ``x.y.z`` format reported
12by the CMake package shipped with Boost ``1.70.0`` and later. The macro
13value is still reported in the ``Boost_VERSION_MACRO`` variable.
14
15The ``OLD`` behavior for this policy is for :module:`FindBoost` to report
16``Boost_VERSION`` as specified in the preprocessor definition
17``BOOST_VERSION`` in ``boost/version.hpp``. The ``NEW`` behavior for this
18policy is for :module:`FindBoost` to report ``Boost_VERSION`` in
19``x.y.z`` format.
20
21This policy was introduced in CMake version 3.15.  Use the
22:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
23Unlike many policies, CMake version |release| does *not* warn
24when this policy is not set and simply uses the ``OLD`` behavior.
