The fact that a separate find_library is called for it and the result
is stored in a separate (user-settable) cache entry means that it is
possible to get two different values. This convention is well established
in several find modules.

The only supported use for PROTOBUF_LIBRARIES is to pass it to
target_link_libraries, and that interprets the 'optimized' and 'debug'
keywords. This is shown in the module documentation example:
target_link_libraries(bar ${PROTOBUF_LIBRARIES})
The documentation makes no other guarantees about the variable value.
