As it is a rather biting constraint, I would test in configure. Many many
moons ago I added this to RQuantLib's configure which is now quaint as the
2.* series rests in compiler heaves:

AC_PROG_CXX
if test "${GXX}" = yes; then
    gxx_version=`${CXX} -v 2>&1 | grep "^.*g.. version" | \\
		       sed -e 's/^.*g.. version *//'`
    case ${gxx_version} in
        1.*|2.*)
	     AC_MSG_WARN([Only g++ version 3.0 or greater can be used with RQuantib.])
	     AC_MSG_ERROR([Please use a different compiler.])   
        ;;
    esac
fi

You could use similar logic to ensure [min, max] intervals for the MySQL
version you want to support.
