Bug 347419

to get drop shadows working the style needs to be built with x11-xcb apparently. unfortunately it being missing during the cmake step is not reported in a suitable fashion. namely it does not show up in the cmake summary but rather the wall of random status output before the summary.

it would be very very very awesome if it could be made to show up in the summary as otherwise it goes unnoticed (as was the case in Kubuntu for example). also since the summary output is more or less a common format it's where one would apply computational parsing to throw warnings on missing dependencies, which is also bypassed by not having it listed in the summary.

example of current output:
[...]
