Re: [jamboost] bbv2-m10: how to differ .obj build dir by using <define> (similar to debug vs release)?

There's no way to represent "define" in build path, however you can created 
your own new features and make it expand to desired defines. Like this:

import feature ;
feature.feature djb-build-kind : standard professional : propagated
composite ;
feature.compose <djb-build-kind>standard : <define>STANDARD_BUILD ;
feature.compose <djb-build-kind>professional :
<define>PROFESSIAONAL_BUILD ;

HTH,
