Autotools uses a versioned shared library name derived from libtool. This patch adds a versioned shared library name to cmake builds for all supported platforms. Binary compatibility for clients build against older cmake generated binary packages of dbus is provided; on unix like os with symbolic links and on Windows with a copy of the shared library. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=74117 Reviewed-by: Simon McVittie <simon.mcvittie@collabora.co.uk>
