Add help compilation to Ubuntu's users

[tamplan]

On Ubuntu 19.04, without this PR, i have got this message:

Either Ayatana Indicators or Ubuntu Indicators are required to build mate-indicator-applet.

with no more help (including README file).

This doesn't look right to me. IIUC, the problem is that the case where you have both Ayatana and Ubuntu indicators is not handled, so results in an error telling you you don't have any instead of both.

IMO the whole test chain should be modified to be simpler and test it all, something like that:

if test "x$with_ayatana_indicators" = "xyes"; then
    use_ayatanaindicator=yes;
    indicator_enforced=yes;
elif test "x$with_ubuntu_indicators" = "xyes"; then
    use_ubuntuindicator=yes;
    indicator_enforced=yes;
elif test "x$have_ayatanaindicator" = "xyes"; then
    use_ayatanaindicator=yes;
    indicator_enforced=no;
elif test "x$have_ubuntuindicator" = "xyes"; then
    use_ubuntuindicator=yes;
    indicator_enforced=no;
else
    AC_MSG_ERROR([Either Ayatana Indicators or Ubuntu Indicators are required to build mate-indicator-applet.])
fi

it doesn't show special messages when one is requested but the other is present, and it selects one over the other if both are present (here, Ayatana's, but it can be swapped easily if wanted -- I have no idea which one should be "best"); but it should cover all cases.

@sunweaver: can you please have a look at this...?

Ok, to be clear, launching just the ./autogen.sh script, i have got the message yet mentioned but informations to compile correctly are given using the command ./configure -h.

Perhaps, and you are right, a better test chain should be studied here to not block the user to compile.

Thanks for your help!

Any progress or can this be closed?

The description Ubuntu Indicators is misleading. It's called simply libindicatoror libindicator-gtk3-devel in fedora.
