[CMake] Problem linking dynamic libraries on MacOSX

[Mike Jackson]

People have been known to use symlinks to solve the problem. There is
the BundleUtilities that help package the .app part. I wrote some
cmake code to do basically what you ate wanting to do. It is a
variation on the BundleUtilities code but works with an executable
outside of an .app bundle with libraries residing in another folder.
