forwarding build type to dependencies with dub

[Johannes Loher via Digitalmars-d-learn]

Is it possible to forward the build type to the dependencies of a dub
project? For example, if I build my project with

dub build -b unittest

is it possible to make dub build the dependencies of my project also
with the unittest build type? Even better would be a way to specify for
which dependencies this should happen.

This would be useful for using dunit
(http://code.dlang.org/packages/dunit). When built with the unittest
build type, it replaces the default unittest handler to give nicer
output about which unittests failed and why etc. If I simply add dunit
as a dependency to my project and build my project as described above,
dunit is not built with the unittest build type and thus the unittest
handler is not replaced and I got the usual assertion error output for
failing unittests.

I tried removing the version(unittest) from the part of dunit, which
replaces the handler, but it always outputs some text, even if no
unittests are being run (if we don't compile with -unittest). Of course
I do not want this ouput when not testing and especially not in release
code...
