Hm. You're right. It seems like no linking takes place with my style.

So here's what I got (I am on windows):

local CODE_ROOT  = [ os.environ CODE_ROOT ] ;

lib hugin : : <variant>release 
<file>$(CODE_ROOT)/dependencies/hugin/Lib/hugin-7.1-vc9.lib ;
lib hugin : : <variant>debug 
<file>$(CODE_ROOT)/dependencies/hugin/Lib/hugin-7.1-vc9d.lib  ;

# ...

[ unit-test speed_of_propagation
              : speed_of_propagation.cpp bayesian hugin
                                     ]

This causes bjam to link with a file named "hugin.lib". The bjam output 
list this file in the files sent to the linker. That's wierd IMO.

I tried replacing the file paths to the exact paths (that is, not using
the $(CODE_PATH) prefix).

Then it worked.

Maybe, just a suggestion, we could emit an error message if the file is 
not found in a <file> directive.

Thanks for the help
