How does Visual Studio know the name of the library?

Question

C++ / C#

I assembled Boost, successfully installed it in the project, everything works, but a question arose.
For the sake of experiment, I tried to build a project without libraries, only with headers.
Removed the path to *.lib files from the "Additional Library Directories", and got this interesting message:

Question - how does the studio find out the exact name of the *.lib library, if the path to it is not registered anywhere?
At first I thought that the library is included in the headers via the "#using" directive, but I didn't find such a line in them:

How does the compiler know the exact name of the library?
Maybe I'm really stupid right now, tell me please

Answer 1

So you have boost connected to include, of course he knows what libraries he needs, connect the old include , and see what will be required.
If you are already interested in searching for files, type in the name of the library and see where it is listed.
