Visual studio 6.0 (VC++ reference issue)

Question

I have the following workspace images of my project

I would like to know what are the highlighted components in Workspace ?
I tried to find out more about it by trying to access its properties but nothing was available. So I deleted them .But know if I try to build my VeCAD_EXE project I get unresolved external symbol errors for the methods defined in CAD_DLL project.
I suppose it acted as some reference to my CAD_DLL project.
But I don't know how do I get those 2 components back again :(.

Any views of how can I achieve this is highly appreciated.

Answer 1

Those are the dependencies that should be built before building VECAD_EXE project. Probably these project produce .lib/.dll that must be linked with main project and because they are missing you receive linking error.

To change dependencies for project go to Project -> Dependencies... menu.
