Would it be possible to use some technique similar to this:
--- project foobar ; exe test : main.cpp ; # NOTE: We need to specify location here in order to avoid # the "duplicate targets" problem. # alias test2 : test/<location>bin2/<define>FOOBAR=2 ; # or <xsl-param>something install bin : test2 ; --- I know it's not literally what you're looking for, but you might be able to adapt it to your needs.
