- stop copying the DLL to OUTDIR
- since that was the main reason for the separation between
  CliNativeLibrary and CliNativeLibraryTarget, merge the targets;
  the newly inherited variables are not expected to cause problems
- the Library remains in layer NONE; the derived CliNativeLibrary
  is in INSTDIR
- hardcode target to URE bin dir for now, no immediate need for
  multiple layers
