Yes, good point. I will build in the source dir if there seems any doubt that 
I have made changes that give spurious bugs.

I think you're right about it not being a high priority, but please find an a 
patch attached that copies the qmldir, qml and icon files into the build area 
so that the apps can be run from there. Maybe something similar needs to be 
done for the translation files, I'm not sure, but for normal debugging 
everything seems to work fine.

The patch just adds some rules like this to copy the files across:

file(COPY ${launcher_QML} DESTINATION ${CMAKE_BINARY_DIR}/launcher)

I don't mind at all if the patch isn't commited, but maybe someone would like 
to experiment.
