cmake: set library names to be the same as with autotools

Browse Source 
libtool has VERSION_INFO [1], cmake has SOVERSION/VERSION instead
(although it has different format). Also libtool has RELEASE [2] while
cmake do not have analog yet [3], hence manual symlinks should be
created.

  [1]: https://www.gnu.org/software/libtool/manual/html_node/Libtool-versioning.html
  [2]: https://www.gnu.org/software/libtool/manual/html_node/Release-numbers.html
  [3]: https://gitlab.kitware.com/cmake/cmake/issues/17652

Plus osx has compatibility_version/current_version dylib properties and
cmake do not have separate properties for them [4], hence manual LINK_FLAGS.
And also there INSTALL_NAME_DIR property which should be adjusted too.

  [4]: https://public.kitware.com/Bug/view.php?id=4383

So after all changes, here is an example before/after for osx and linux:

  # osx
    # autotools
    .libs/libevent_pthreads-2.2.1.dylib
    .libs/libevent_pthreads.dylib -> libevent_pthreads-2.2.1.dylib
    /usr/local/lib/libevent_pthreads-2.2.1.dylib (compatibility version 2.0.0, current version 2.0.0)
    # cmake
      # before patch
      lib/libevent_pthreads.2.2.0.dylib
      lib/libevent_pthreads.dylib -> libevent_pthreads.2.2.0.dylib
      @rpath/libevent_pthreads.2.2.0.dylib (compatibility version 2.2.0, current version 0.0.0)
      # after patch
      lib/libevent_pthreads-2.2.1.dylib
      lib/libevent_pthreads.dylib -> libevent_pthreads-2.2.1.dylib
      /vagrant/.cmake/inst/lib/libevent_pthreads-2.2.1.dylib (compatibility version 2.0.0, current version 2.0.0)

  # linux
    # autotools
    .libs/libevent_pthreads-2.2.so.1 -> libevent_pthreads-2.2.so.1.0.0
    .libs/libevent_pthreads-2.2.so.1.0.0
    .libs/libevent_pthreads.so -> libevent_pthreads-2.2.so.1.0.0
    # cmake
      # before patch
      lib/libevent_pthreads.so -> libevent_pthreads.so.2.2.0
      lib/libevent_pthreads.so.2.2.0
      # after patch
      lib/libevent_pthreads-2.2.so -> libevent_pthreads-2.2.so.1
      lib/libevent_pthreads-2.2.so.1 -> libevent_pthreads-2.2.so.1.0.0
      lib/libevent_pthreads-2.2.so.1.0.0
      lib/libevent_pthreads.so -> libevent_pthreads-2.2.so.1.0.0
