In such case you can use:

bin_PROGRAMS=foo
foo_SOURCES= \
        foo.c \
        foo.h

.c.moc:
        moc $< -o $@

.h.moc:
        moc $< -o $@

BUILT_SOURCES = $(shell cat $(foo_SOURCES) | sed -n 
's/^\#.*include.*"\(.*[.]moc\)".*$$/\1/p')


Although there is a GNU make dependency on $(shell ...). I hope the
cross-make(1) compatible way is:


bin_PROGRAMS=foo
foo_SOURCES= \
        foo.c \
        foo.h

.c.moc:
        moc $< -o $@

.h.moc:
        moc $< -o $@

BUILT_SOURCES = built_sources
.PHONY: built_sources

./$(DEPDIR)/.moc_deps: $(foo_SOURCES)
        cat $(foo_SOURCES) | sed -n 
's/^\#.*include.*"\(.*[.]moc\)".*$$/built_sources: \1/p' >$@

include ./$(DEPDIR)/.moc_deps


There is a GNU make(1) warning message
        Makefile:1170: .deps/.moc_deps: No such file or directory

, I hope some non-GNU make(1)s do not bail out on this; AFAIK automake(1) also
uses this approach.

P.S.: It is not fair to reply offlist mails not intended for the list to the
      list.
