libdbusmenu-qt cannot build docs if doxygen is present

[ken@…]

I'm looking at what qt5 modules are needed for packages in the book or otherwise likely to be used (e.g. extra kf5 apps). For this package I could not crib the work of others :)

Builds fine using the book's default instructions:

Note that we do not mention QJSon - there is an old tarball in conglomeration at origin state, but it needs qt4 which I assume is why we do not mention it.

We say "-DWITH_DOC=OFF: This option is set to avoid building the API documentation. Omit it if you have doxygen installed and want the documentation."

But that too needs qt4:

ken@virtx86_64 ~/libdbusmenu-qt-0.9.3+16.04.20160218/build $cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release -Wno-dev ..

That package has not been updated in six years. We ought to just remove any reference to the docs, including doxygen.

The best I can tell, the only thing that needs libdbusmenu-qt is knotifications in kf5. Arch shows a few other packages, but none of those are in BLFS.

Drilling down a bit, the only thing knotifications uses is two lines in one file, src/kstatusnotifieritem.cpp, and those are optional:

#if HAVE_DBUSMENUQT
            new DBusMenuExporter(d->menuObjectPath, menu,
                                 d->statusNotifierItemDBus->dbusConnection());
            Q_EMIT d->statusNotifierItemDBus->NewMenu();
#endif

Thanks. For some reason I failed to find the package when looking at Arch. I'm short of cycles at the moment, but I'll get a round tuit.

(Needs a farcebook login to continue.) The switch to disable docs is still needed, so I'll change the explanation.
