+    imv-swid: Use pkg-config to check for libjson-c
+    
+    The package/library is called libjson-c on recent distributions.
+    Some like Ubuntu 14.04 provide symlinks with the old name but these
+    will eventually disappear.  Using pkg-config allows us to easily check
+    for it (with a fallback) and configure the proper compiler flags.
+    
+    Fixes #663.
