FindBoost-fphsa
---------------
* The :module:`FindBoost` module was reworked to expose a more
consistent user experience between its config and module modes
and with other find modules in general.
* A new imported target ``Boost::headers`` is now defined (same
as ``Boost::boost``).
* New output variables ``Boost_VERSION_MACRO``,
``Boost_VERSION_MAJOR``, ``Boost_VERSION_MINOR``,
``Boost_VERSION_PATCH``, and ``Boost_VERSION_COUNT``
were added.
* The internal logic for determining the value for
``Boost_FOUND``, for version and component checks, and
for reporting the result to the user was replaced with
the :module:`FindPackageHandleStandardArgs` module. (This
fixed a bug that sometimes printed wrong status
messages in config mode.)
* The ``QUIET`` argument passed to :command:`find_package` is no
longer ignored in config mode.
* *Known issue*: The CMake package shipped with Boost ``1.70.0``
ignores the ``QUIET`` argument passed to :command:`find_package`.
This is fixed in the next Boost release.
* The input switch ``Boost_DETAILED_FAILURE_MSG`` was
removed.
* ``Boost_VERSION`` now reports the version in ``x.y.z``
format in module mode. See policy :policy:`CMP0093`.
