playing around some more with bjam and reading your documentation
(again) I came up with following solution. I just want to make sure that
this is intended behaviour (and thus to make sure that this 'trick' will
keep working in the future)
import project ;
project.initialize $(__name__) ;
project user-config ;
: # sources
: # requirements
: # default-build
lib libfoo : mpi.cpp /user-config//mpiheaders ;
So basically I just defined an alias target with usage-requirements to
propagate them to the libraries that need those include-directories.
What I am not sure about is that the documentation of the alias rule
does not talk about usage-requirements but I just thought it would be
similar to the other rules. If you can confirm this it would be nice to
complete the documentation. I can do that if you want (and you tell me
where exactly) ?
