It may be ideal if all contributors learned and updated inputs to
all the build process options like cmake, make, and autoconf at the
same time as they futz with the code they build (in other words, a
change that makes such a list to empty includes cmake update), but
different people chipping in with help in their strong areas and
polishing the system as a whole as a collaborative effort is
probably the best practical alternative.

Thanks.
