[CMake] Browser plugin bundle for Mac OSX

[Gino]

Good morning to everybody.
I'm here to ask you some help, hints, or at least an hyperlink to some good documentation, on how create plugin bundles with CMake on MacOSX.
Currently I'm able to obtain a plugin bundle with cmake, that simply doesn't work.
So I thought it was the executable, and I took the executable from inside this plugin bundle builded with cmake, and copied it inside an Xcode generated plugin bundle, which worked, and it works also with this new executable.
Any hint?
Thanks in advance.
