Set library version correctly
Set library version correctly

We were using SOVERSION to set the full build version of our shared
libraries.  SOVERSION should only contain the first number of the build
version triple.  The VERSION property is what should contain the
library's full build version.  Also, the CMake build file now includes a
description of when and how to update the library version.  (It
*shouldn't* match the package's release version.)
