[CMake] fixup_bundle: installing multiple executables that depend on the same libraries

[Michael Jackson]

I ended up creating a variation on fixup_bundle for command line tools
on OS X. It basically copies the app into "bin/" and depended
libraries into "lib/" and then runs install_name_tool on the
executables to make them find the libraries in "lib/".

You can find examples of the cmake code and configurable shell scripts here:
