Augment instead of replace maude_DEPENDENCIES

[Daily, Jeff A]

Some of my test programs require generated input files - perhaps one per test 
program.  I want to generate them as dependencies of the particular test 
programs which use them.  However, I don't want to replace the dependencies 
which automake already determines for my test programs.  maude_DEPENDENCIES 
appears to be the correct way to go, but if I replace what automake generates 
automatically, then I have to recreate what automake would have done for me.

check_PROGRAMS = tests/FillValue
tests_FillValue_SOURCES = tests/FillValue.C
tests_FillValue_DEPENDENCIES = data/FillValue.nc libpagoda.la
.cdl.nc:
        $(NCGEN) -o $@ $<
EXTRA_DIST = data/FillValue.cdl
CLEANFILES = data/FillValue.nc

Alternatively, I could generate all input files as part of some other target or 
dependency.  I considered the check-local target, but since there's no 
guarantee on the order of check-local versus check, I can't guarantee that the 
input files are generated prior to my tests executing.  I could then use 
BUILT_SOURCES, but I don't want the test input files generated unless they are 
truly needed.

Is my only recourse to replace maude_DEPENDENCIES?  It would be nice to augment 
what automake provides rather than replace it.
