Thanks for your comment.  After reading through the information on the boost site I am not sure how to "auto-link" except to choose the path in the IDE.
Is there something within boost that I need to do to activate this?

Here's a question: are you using Boost's auto-linking feature?  I
suspect not, and that this is the cause of your issues.
