These are both embedded in the shared library binary +and can be checked with the ``otool -L <binary>`` command. + +It should be noted that the ``MACHO_CURRENT_VERSION`` and +:prop_tgt:`MACHO_COMPATIBILITY_VERSION` properties do not affect the file +names or version-related symlinks that CMake generates for the library. +The :prop_tgt:`VERSION` and :prop_tgt:`SOVERSION` target properties still +control the file and symlink names. The ``install_name`` is also still +controlled by :prop_tgt:`SOVERSION`. + +When ``MACHO_CURRENT_VERSION`` and :prop_tgt:`MACHO_COMPATIBILITY_VERSION` +are not given, :prop_tgt:`VERSION` and :prop_tgt:`SOVERSION` are used for +the version details to be embedded in the binaries respectively. +The ``MACHO_CURRENT_VERSION`` and :prop_tgt:`MACHO_COMPATIBILITY_VERSION` +properties only need to be given if the project needs to decouple the file +and symlink naming from the version details embedded in the binaries +(e.g. to match libtool conventions). |
