The subject says it all - I want my Makefile to correctly recompile everything when I change my .hxx header files. It doesnt do that at the moment - it requires a manual make clean then make.

Use the makedepend utility.  That will parse your source files and learn all the include files your sources depend on.  Then, it will add extra dependencies onto your Makefile.

To use makedepend, add this entry to your Makefile.  Make sure SRCS is a list of all of your source files
depend:
          makedepend -- $(CFLAGS) -- $(SRCS)

After you edit your Makefile, run "make depend" to make the new line in the Makefile execute.  Look in your Makefile afterwards and you will see that all the necessary include dependencies have been added.
