For shared libraries and executables on Windows the :prop_tgt:`VERSION`
attribute is parsed to extract a ``<major>.<minor>`` version number.
These numbers are used as the image version of the binary.
Mach-O Versions
^^^^^^^^^^^^^^^
For shared libraries and executables on Mach-O systems (e.g. OS X, iOS),
the ``SOVERSION`` property corresponds to *compatibility version* and
:prop_tgt:`VERSION` to *current version*. See the :prop_tgt:`FRAMEWORK` target
property for an example. Versions of Mach-O binaries may be checked with the
``otool -L <binary>`` command.
