I recently had the same problem.
On windows you need to copy the ‘chaiscript_stdlib-5.6.0.dll’ into a location where the dynamic library loader can find it. The easiest way to do that is to copy it into the same folder as the executable. This file can be build using the Visual Studio project of the same name.
On Linux/Mac I think the same principle applies, except the file woud be chaiscript_stdlib-5.6.0.so or similar. It appears that this file is built as part of the standard ‘make’ command.
