Have a look at Klemens' experimental library
https://github.com/klemens-morgenstern/sam
It contains an async condition variable fully compatible with asio

The other way is to use an asio steady_timer. You would cancel the timer in
order to signal the condition. The waiter would see this as an
*operation_aborted* error, which would indicate, "you have been signalled".
You can set the timer to expires_at(std::chrono::steady_clock::max()) to
indicate that the wait should be indefinite.
