10 # This script ingests libraries and frameworks into an existing .app bundle and
11 # then uses install_name_tool to fixup the references to the newly embedded
12 # libraries so that they all refer to each other via "@executable_path."
14 # The main intent (and simplifying assumption used for developing the script)
15 # is to have a single executable .app bundle that becomes "self-contained" by
16 # copying all non-system libs that it depends on into itself. The further
17 # assumption is that all such dependencies are simple .dylib shared library
18 # files or Mac Framework libraries.
20 # This script can be used as part of the build via ADD_CUSTOM_COMMAND, or used
21 # only during make install via INSTALL SCRIPT.

30 'input_file' should be the main executable inside a Mac bundle directory structure.
31 For example, use 'bin/paraview.app/Contents/MacOS/paraview' from a ParaView binary dir.
33 'extra_libs' should be a semi-colon separated list of full path names to extra libraries
34 to copy into the bundle that cannot be derived from otool -L output. For example, you may
35 also want to fixup dynamically loaded plugins from your build tree and copy them into the
