Perfect! Thanks.

Thanks, Paul. Got it.
OK, gentlemen, the only remaining problem with the attached makefile
is that it fails if the .deps directory doesn't exist.
if g++ -MT documentPageCache.o -MD -MP -MF
".deps/documentPageCache.Tpo" -c -o
documentPageCache.o ../documentPageCache.cpp; \
then mv -f ".deps/documentPageCache.Tpo"
".deps/documentPageCache.Plo"; else rm-f
".deps/documentPageCache.Tpo"; exit 1; fi
../documentPageCache.cpp:350: fatal error: opening dependency
file .deps/documentPageCache.Tpo: No such file or directory
Clearly, I can create a rule
mkdepsdir
test -d $(depsdir) || mkdir $(depsdir)
$(objdir)/%.o: $(srcdir)/%.cpp $(MOCS) mkdepsdir
Indeed, it works. However, is it the "recognized" way to do this? I
don't see anything equivalent in an automake generated makefile
(although it does store dependencies in .deps).
