dependencies needed to use the library, to build it and to test it (well, 
there is fourth also: to build its docs, but we'll ignore it for now). The 
three sets can be very different. If I'm not mistaken (let Peter correct me 
if I am), bpm takes care of the first two sets without distinguishing 
between them and ignores the third one because it typically adds many more 
dependencies that aren't needed if you don't intend to run the library 
tests.

bpm currently does whatever the dependency file tells it to.

For a source release, this dependency file would presumably tell it to fetch 
all libraries need to build (and it does for the example distribution).

For a binary release, the dependency file would tell it to fetch all 
libraries needed for use.

I could in principle add an option to fetch the test dependencies and use 
them instead.

The dependency file for the example distribution is

http://pdimov.com/tmp/pkg-develop-1612497/dependencies.txt.lzma

created by the line

dist\bin\boostdep.exe --track-sources --list-dependencies | xz --format=lzma 
 > %OUTDIR%\dependencies.txt.lzma

in the package.bat script.
