VERSION
-------

What version number is this target.

For shared libraries VERSION and 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
executables VERSION can be used to specify the build version.  When
building or installing appropriate symlinks are created if the
platform supports symlinks.  For shared libraries and executables on
Windows the VERSION attribute is parsed to extract a "major.minor"
version number.  These numbers are used as the image version of the
binary.
