ENH: Finished CMAKE_<CONFIG>_POSTFIX feature and documented it. The value of this variable is used when a library target is created to initialize the <CONFIG>_POSTFIX target property. The value of this property is used (even for executables) to define a per-configuration postfix on the name of the target. Also enabled use of the OUTPUT_NAME property for non-executable targets.
