Quassel IRC

When compiling from latest Git (SHA 546e609b7e2fa683e8b7b90d6079dd3a80ed4c6b), I get the following error:

Upon inspection, the QtScript module is not being linked (no -lQtScript): <builddir>/CMakeFiles/quassel.dir/build.make

Adding the -lQtScript manually makes it compilable (but fails on the next link; adding yet again makes that link as well).
