[Qt-embedded-interest] Qt Embedded on ARM Development Board

[Chris Burke]

The Qt app cannot find the lib directory. It needs to be located on the 
device even if the application is built statically. Copy the lib 
directory over from your desktop to the embedded device keeping the same 
exact directory structure as it is looking for when you run the application.
