Can you confirm that it runs when launched with Cabbage, i.e., outside a host? The CabbageInclude feature is not yet supported in version 2. it's on my list of things to add. For now you may have to drop the .svg files into the plugin bundle. I think there was a thread about this here from a few months back. I'll take a look.
 Right-click the .vst bundle and hit 'Show Contents'. Then copy your .svg files into the Contents folder. Then try it again. If it still doesn't work, copy them to the MacOS folder. One of those should do the trick.
