cmake: Generate an internal 'Labels.json' file next to 'Labels.txt' 

In each internal target directory we generate a "Labels.txt" file
containing labels for that target and its sources, but it uses an
internal format.  In order to make the list of labels easier to
publish, use a json format and call it "Labels.json".

Since we now use jsoncpp headers, link CMakeLib to the jsoncpp library.
