Just for my education, what does find_program() look for?  Installed
packages, or a program on your $PATH?  I am guessing that the answer
is the latter, in which case it is not like "it makes more sense to
check for git-clang-format"---rather it is "it would not work at all
if we looked for clang-format", no?

Thanks.
