[llvm] r257459 - Explicitly enable OBJECT library "target".

[Axel Naumann via llvm-commits]

New Revision: 257459

URL: http://llvm.org/viewvc/llvm-project?rev=257459&view=rev
Log:
Explicitly enable OBJECT library "target".

With this, one can build a lib from the objects of other libs:
set(SOURCES
  $<TARGET_OBJECTS:obj.clingInterpreter>
  $<TARGET_OBJECTS:obj.clingMetaProcessor>
  $<TARGET_OBJECTS:obj.clingUtils>
  )
