*Blush*, I don't know how I missed that.  Thanks.

There is still the issue that module files don't get rebuild if they are
deleted,

make[2]: *** No rule to make target `include/petscmat.mod', needed by `CMakeFiles/petscdm.dir/src/dm/f90-mod/petscdmmod.F.o'.  Stop.
make[1]: *** [CMakeFiles/petscdm.dir/all] Error 2

I don't seem to be able to regenerate the module by any lightweight
procedure (make -B SpecificTarget works).  Perhaps that scenario where
module files are deleted independent of the object/libraries is
artificial, but it's not really correct for the build to break if they
are deleted.
