There are 3 ways to link QL into your project:
1) #include <ql/auto_link.hpp> - this directive appears in
quantlib.hpp.
2) List the QuantLib static library explicitly in your
project's link dependencies. Not convenient nor recommended,
because the QL lib has a different name under each
configuration, e.g. QuantLib-vc80-mt-s-0_9_0.lib for Release,
QuantLib-vc80-mt-0_9_0.lib for Release CRTDLL, etc.
3) If your project and QuantLib reside in the same VC solution
file, and if you make the former dependent on the latter as you
explained in your message, then VC automatically gets the link
dependencies right even in the absence of 1) and 2).
If you needed 1) initially but don't any longer, maybe it's
because you implemented 3) in the interim.
Bonne journée,
Eric
