I assume you know how to use and link a library in general, so I won't go
into this.

AFAIK, VC's major versions are not binary compatible with each othe (which
is exactly what a major version change usually signals). IOW, you need
different libs for different C++ compilers (which is not only true for VC,
btw). If you only have one, use the compiler it was compiled for.
