Cool ... so I think a workable solution for Tobias would be to leave 
CPACK_BUNDLE_STARTUP_COMMAND empty, ensure that the Info.plist specified 
with CPACK_BUNDLE_PLIST runs the correct applet file, then use

INSTALL(FILES /path/to/applet DESTINATION ../MacOS/applet)

to put the applet where it belongs in the bundle, without renaming it.

Since the bundle generator relies on the user to generate their own 
Info.plist anyway, it sounds as if renaming the startup command is 
heavy-handed and should be replaced with a straight copy.

Cheers,
Tim
