Do something like the following lines in a bash window. Then rebuild 
bibletime by either deleting the build directory or just the 
build/CMakeCache.txt and doing a clean build.

export QTDIR=/usr/local/Trolltech/Qt-4.6.0-debug
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib

The LD_LIBRARY_PATH is needed at runtime.
