Static libraries cannot link anything. If you use a static library, in
the absence of autolink pragmas, the onus is on you to link whatever is
needed by the libraries.

In this case, you in your project appear to not be linking in the
library defining InterlockedCompareExchange, which IIRC is located in
Kernel32.lib.
