...link static libraries built from another project?

How do I link a library into the build of my application?

If the library project is in the same solution as the application project then all you need to do is make the application project dependent on the library project using the Project > Dependencies dialog.

Alternatively, if it is an externally built project you want to link with, you can add the path to the library file to the Linker > Additional Input Files project property.
