What version number is this target.
For shared libraries
VERSION and :prop_tgt:
SOVERSION can be used
to specify the build version and API version respectively. When building or
installing appropriate symlinks are created if the platform supports
symlinks and the linker supports so-names. If only one of both is
specified the missing is assumed to have the same version number. For
VERSION can be used to specify the build version. When
building or installing appropriate symlinks are created if the

Windows Versions ^^^^^^^^^^^^^^^^
For shared libraries and executables on Windows the
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),
SOVERSION property correspond to compatibility version and
VERSION to current version. See the :prop_tgt:
property for an example. Versions of Mach-O binaries may be checked with the
otool -L <binary> command.
