cmake: Fix find_library for ubusd and examples/server Both ubusd and cli TARGET_LINK_LIBRARIES reference ${json} which is obtained via find_library(), but since the find_library() is searched after the TARGET_LINK_LIBRARIES for ubusd, ubusd always gets an empty ${json} variable. examples/server also links against libjson-c, but we were not setting TARGET_LINK_LIBRARIES accordingly, so do that too with ${json} appended. This was causing linking errors for ubusd and then examples/server using an external toolchain (stbgcc-4.8-1.x).

cmake: add a possibility to set library version Add a new `ABIVERSION` define which allows to control the SOVERSION used for the built shared library.
