Targets can have properties that affect how they are built.

         SET_TARGET_PROPERTIES(target1 target2 ...
                               PROPERTIES prop1 value1
                               prop2 value2 ...)
...
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.
