Never mind. Sometimes it is bad to work late at night. I had convinced myself the following did not work.

For the record, here's the fixed makefile

I'm using Qt 4's moc to generate source files in an autotools project.

The pattern looks something like

cat <<_EOF >
# Makefile fragment
test_SOURCES=a.cpp b.cpp
test_META=a.hpp b.hpp
test_LDADD = $(test_META:%.hpp=%_moc.$(OBJEXT))

%_moc.cpp : %.hpp
        $(QT_MOC) -o $@ $<

$(DEPDIR)/%_moc.Po :
        @touch $@
include $(test_META:%.hpp=$(DEPDIR)/%_moc.Po)


The main problem with this is that it spews warnings about missing deps files the first time make is run. It would be nice to properly hook into configure's depfiles command to avoid these warnings. Likewise configure is generating a bogus file named ".deps/$(test_META:%.hpp=%_moc.Po". Otherwise it seems to work.
