New in version 3.15.
FindBoost reports Boost_VERSION in x.y.z format.
In CMake 3.14 and below the module would report the Boost version
number as specified in the preprocessor definition BOOST_VERSION in
the boost/version.hpp file. In CMake 3.15 and later it is preferred
that the reported version number matches the x.y.z format reported
by the CMake package shipped with Boost 1.70.0 and later. The macro
value is still reported in the Boost_VERSION_MACRO variable.
The OLD behavior for this policy is for FindBoost to report
Boost_VERSION as specified in the preprocessor definition
BOOST_VERSION in boost/version.hpp. The NEW behavior for this
policy is for FindBoost to report Boost_VERSION in
x.y.z format.
This policy was introduced in CMake version 3.15.
It may be set by cmake_policy() or cmake_minimum_required().
If it is not set, CMake does not warn, and uses OLD behavior.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
