[V2] Moc generator not adding generated sources to list of includes

Hi,

I'm trying to get the Moc generator to automatically add its output 
directory to the list of compiler includes.

Essentially I have a Jam file that looks like this:

# Jam file begin
project somelibrary
: build-dir $(BUILDDIR)
;

lib libname
: [ glob *.cxx ]
QObjectHeader1.h
QObjectHeader2.h
: <include>.
: : <include>.

#Jam file end

The two .h files are in there because they are QObjects and need to be 
compiled by the Moc compiler. The output is a .moc.cxx file (I modified 
the qt.jam file so that instead of CPP(moc_%) it says CPP(%.moc)) that 
is included by the appropriate QObjectHeader cxx file. The problem is 
that the .moc.cxx files are generated fine, but they build directory is 
not added to the list of gcc compiler includes.

If I do this:

lib libname
: [ glob *.cxx ]
QObjectHeader1.h
QObjectHeader2.h
Temp.ui
: <include>.
: : <include>.

In my Jamfile and just 'touch' the 'Temp.ui' file it works fine (ie: the 
build directory is added to the list of compiler includes) but it fails 
when uic tries to compile the Temp.ui file.

So my question is:

Is there any way to fix this so that QObject header file -> moc.cxx 
generation works the way I want it to? If not, is there some way to 
determine the build directory being used such that I can add it to the 
list of includes (can I modify the list of includes inside of a rule?) ?

Also, has anyone written a scanner that automatically looks in header 
files for the Q_OBJECT line, and if it is then that file is 
automatically added to this list of sources?

I'm still really new with Boost.Build and I've tried reading through all 
of the .jam source files, but a lot of them are really complex for a 
beginning.

Thanks,
