[boost] Boost linked example

Could someone, please, point me to an example (in the Boost source, i.e. a file in the libs sub-folder) that would require (with certainty) a built library. Which library don't matter. I've tried some date-time examples and boost::random::random_device, but it works, while I hoped it wouldn't. The latter can also mean I have some strays, but then I know that. I would like to check vcpkg static-static linking for Boost. Thanks, degski -- *"If something cannot go on forever, it will stop" - Herbert Stein*
