That's the way it's working for me.  I have "project apago :
requirements <variant>debug:<define>_DEBUG ...".  You might try putting
the includes directly on the project instead of using an alias.  Like this:

    project myproj : requirements <include>h1_dir <include>h2_dir ;

Also, I just noticed that in an earlier email, you have
"<include>h2_dir>;"  If that's what you actually have in your Jamroot,
that would cause a problem, since it would add "h2_dir>;" as an include
path and would not terminate the alias target, since there has to be a
space before the semi-colon (";").  If that's what you have, you should
try changing that first.

Hope this helps.
