要链接到哪个 boost 库？

Question

Okay so I've got a very small program containing these three boost imports:

#include <boost/asio.hpp>
#include <boost/lexical_cast.hpp>
#include <boost/thread.hpp>

But that's just an example I'd like an answer that's applicable to other headers as well if possible. Now taking a look into /usr/lib results in a list of 39 static library objects I could possible link to (or rather put into my CMakeLists.txt): List of libraries

How can I know which library is implementing which boost header in /usr/include/boost?

This is the relevant part of my CMakeLists.txt:

set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED OFF)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost
    1.63.0
    REQUIRED
    ????
)

Boost libraries has a naming convention defined in the documentation here . Eg libboost_thread.a is a static library for Boost.Thread .

In the header source you can find related library name, eg in boost/thread.hpp there is:

//  See www.boost.org/libs/thread for documentation. 

Next you need to understand library is header-only or not. Check the list here .

Some libraries requires the other Boost libraries, eg Boost.Asio requires Boost.System and Boost.Regex in some cases. Check library usage documentation to understand such dependencies.
