[Qt5-feedback] The #include directives for Qt Essentials and Qt Add-on modules

[lars.knoll at nokia.com]

Yes, that's how it would look. And the advantage is that you only need to
specify one include path on the compiler command line.

Pushing it all into one directory is a no-go for many reasons. We're
currently talking about how the include statements would look like. That
depends on what you specifyon the compiler command line.

So instead of looking at the include statements we should probably rather
write down how the directory structure of Qt essential and Qt addon
includes look like. On Unix, they'd all be under /usr/include so something
like /usr/include/qt5/ should be the common base dir.

In there, it should IMO look something like:

QtCore/Qcore
QtCore/qlist.h
...
QtGui/QtGui
QtGui/Qpainter
...
QtAddons/MyAddon/MyAddon
QtAddons/MyAddon/myheader.h
QtAddons/AnotherAddon/...


Cheers,
Lars
