etc. It is not obvious how to get the build to start again; nor was it obvious
(to me) that previous options were cached. Maybe print at start of build,
"Using options from scons/options.cache: enableMpi=false, someotherstuff=...."
That way the user knows both which options are used and how to start fresh.
