+If Boost was built using the `boost-cmake` project or from `Boost 1.70.0` on it provides a package
+configuration file for use with find\_package's config mode. This module looks for the package
+configuration file called BoostConfig.cmake or boost-config.cmake and stores the result in CACHE entry "Boost_DIR".
+If found, the package configuration file is loaded and this module returns with no further action.
+See documentation of the Boost CMake package configuration for details on what it provides.
+
+Set `Boost_NO_BOOST_CMAKE to ON`, to disable the search for boost-cmake.
