Hi, I would like to propose this patch to improve cmake-based building on OS X - it allows building a full OS X bundle.
See bug #8188 http://www.lyx.org/trac/ticket/8188 and the patch cmake-osx.patch that does not break autotools http://www.lyx.org/trac/raw-attachment/ticket/8188/cmake-osx.patch It basically adds instructions in the cmake files to include all the linked libraries and resources necessary to start LyX.
