From Eric Wing,

"Attached is a patch allows access access to the CMake MACOSX_BUNDLE
option. Now SETUP_APPLICATION and SETUP_EXAMPLE take an additional
optional parameter that specifies if the program is a command line
application or a GUI application (think: IS_COMMANDLINE_APP). Passing
1 means true (is_commandline_app). Passing 0 or omitting the parameter
means false.

I changed the scripts for osgversion and osgunittests to support this
option because I believe they are command line apps. Are there any
others?"
