BBv2 m10: recursive dependency

Hi,
I have a problem using boost.build v2 m10. I have the Jamfile below 
which builds an executable test. Now I want to build it with the gmp 
library when I enable the feature with-gmp. However, it does not work, 
because gmpxx will depend on itself. Is there a way to make all targets 
(except this lib) to depend on gmpxx? Or is this approach just not the 
right way? I cannot just put the gmpxx dependency into the requirements 
of test, because in the real environment there are several targets in 
different subdirectories and I just dont want to add the dependency to 
each subproject.

Jamfile.v2
------------------------------------------

import feature : feature compose ;

lib gmpxx : : <search>$GMPROOT/lib
: : <include>$GMPROOT/include ;

feature with-gmp : off on : propagated composite ;
feature.compose <with-gmp>on : <define>DD_USE_GMP <source>gmpxx ;

project dd ;

exe test : test.cpp ;
