Qt QtDBus compilation

To add DBUS to Qt compilation, add following switch

./configure -opensource -dbus ....<br />

If you get following error:

The QtDBus module cannot be enabled because libdbus-1 version 0.93 was not found.<br />
Turn on verbose messaging (-v) to ./configure to see the final report.<br />
If you believe this message is in error you may use the continue<br />
switch (-continue) to ./configure to continue.<br />

It's necessary to install libsbus:

sudo apt-get install libdbus-1-3<br />
Reading package lists... Done<br />
Building dependency tree<br />
Reading state information... Done<br />
libdbus-1-3 is already the newest version.<br />

and also developer package:

sudo apt-get install libdbus-1-dev<br />

Now everything should work correctly.
