I copy images and other files to lib/ocarina/ during the build to make
installing easier. The lib directory should always be relative to the
bin (executable) path, so I can easily find the lib path based on
executable path (/proc/self/exe).
I can also use this to find bugs in the buld process, such as adding a
file to the images/ directory but forgetting to add it as an install
target.
