These are space separated in the final value, and passed to the linker
as is, so you should set it like this:

set( CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS}
/NODEFAULTLIB:\"${lib}\"" )

(Double-quote the whole thing, so the space is embedded in the string,
rather than used by cmake as an argument separator for the set
command.)
