Multiple projects in one workspace

[gayan]

Is it possible to have multiple projects in one workspace where the symbols are visible across all projects?

My requirement is to use the symbols of certain libraries in a project. In VS, I create a solution with multiple projects and the symbols defined in the source code of the libraries are automatically available in my main project.
Unfortunately, I could not create multiple projects under one workspace in c::b.
Is there a way to achieve this and if not, is there an alternate method?
