For Predef <https://github.com/boostorg/predef/tree/develop/tools/check>
with documentation for usage here <
https://www.boost.org/doc/libs/1_68_0/doc/html/predef/check_utilities.html>.

For Config <https://github.com/boostorg/config/tree/develop/checks> and
documentation for that here <
https://www.boost.org/doc/libs/1_68_0/libs/config/doc/html/boost_config/build_config.html
