Hi,

Thanks very much, Paul.

I think I could write a wrapper so that all generated files from
'a.spec' are put in a unique directory, say a.spec.dir. The wrapper will
be able to figure out what all got generated and change the CC_FILES
variable.

Which of the following would be better?

(1) CC_FILES = a.spec.dir/Foo.cc a.spec.dir/Bar.cc

or

(2) CC_FILES = Foo.cc Bar.cc
    # the wrapper script moves the files from a.spec.dir to ..

If I use the first one, I can easily write a 'clean' target:

clean::
        rm -rf a.spec.dir
