that's another of those features which the automake maintainer doesn't 
agree with.

It's possible to make your install-target depend on the file
that you want to install, but doing that for several files can be tedious.
I do this in regular makefiles, for instance

$(INSTALLDIR)/foo: $(SRCDIR)/foo
        $(INSTALL) $(SRCDIR)/foo $(INSTALLDIR)/foo

...but don't expect to see automake support that (or anything equivalent).
automake is designed to reduce the available choices...
