Hi, 

I’m a pretty heavy boost-build user (using for 3 years now) - I think it’s an awesome system even if I wrestle with the complexity sometimes.

I just noticed that the release build of my application includes a -L “…/debug/lib” library path as well as a -L “…/release/lib” path.
I don’t want the -L “…/debug/lib” path in there because the release application is linking to debug libraries and while it works, it’s slow.

I have about 20 Jam files throughout my system so I don’t include them here unless asked to.

How do I figure out from where and why this -L “…/debug/lib” path is being inserted into the command line?

Here’s the command line (generated with "bjam bundle release -n”
