'Undefined reference to UdevQt::......' error encountered while building kdelibs

[Akshat Tandon]

While building kdelibs using kdesrc-build I am encountering
"undefined reference to `UdevQt::..........."
Even after installing udev from the default ubuntu repositories I get the
same error.
How to resolve it?

This is the exact error:
