Take a look at gnuradio-core/src/lib/general/Makefile.am to see how we
do it there.

FYI, this is the Makefile rule that runs the code generator:

$(GENERATED_H) $(GENERATED_I) $(GENERATED_CC): $(CODE_GENERATOR)
        PYTHONPATH=$(top_srcdir)/src/python srcdir=$(srcdir) 
$(srcdir)/generate_all.py


All of the $(srcdir) and $(top_srcdir) stuff is required to make this
work when doing VPATH builds.  That is, builds where the source and
objects are in different directories.
