This is already there. Not word for word but in  the sense.

AC_ARG_WITH(
    [doxygen],
    AS_HELP_STRING(
        [--with-doxygen],
        [Specifies the doxygen executable to use when generating ODK C/C++
         documentation. --without-doxygen disables generation of ODK C/C++
         documentation. Not relevant in the --disable-odk case.])
    [
                          Usage:     --with-doxygen=<absolute path to doxygen executable>
    ],,
    [with_doxygen=yes])

OK, I know people don't even look at ./configure --help, but later:

if test "$enable_odk" = no; then
    unset DOXYGEN
else
    if test "$with_doxygen" = no; then
        AC_MSG_CHECKING([for doxygen])
        unset DOXYGEN
        AC_MSG_RESULT([no])
    else
        if test "$with_doxygen" = yes; then
            AC_PATH_PROG([DOXYGEN], [doxygen])
            if test -z "$DOXYGEN"; then
                AC_MSG_RESULT([no])
                AC_MSG_ERROR([doxygen not found in \$PATH; specify its pathname via --with-doxygen=..., or disable its use via --without-doxygen])
            fi
        else
            AC_MSG_CHECKING([for doxygen])
            DOXYGEN=$with_doxygen
            AC_MSG_RESULT([$DOXYGEN])
        fi
    fi
fi
AC_SUBST([DOXYGEN])

it also mentions --without-doxygen. And again, I don't think it's hard to map
"doxygen not found" to $whathever_command_to_install_doxygen.

In any case I'll stop here, it just began with a wrong assumption of people what
apt-get build-dep does (and I do believe that yum build-dep has the same issue)
and that it might be really hard to just install doxygen (I understand that you
maybe don't want to look up configure flags, but...)
