The CMake language does not actually know anything about generator
expressions.  They are just strings like any other command arguments
as far as it knows.  See the command argument syntax documentation
here:

 http://www.cmake.org/cmake/help/v3.0/manual/cmake-language.7.html#command-arguments

In order to ensure the command receives a generator expression in
its entirety it should be double-quoted if it contains any literal
spaces or ${var} evaluations that may have ; in them.  Otherwise
it is not necessary to quote and sometimes looks nicer not to.  It
is always safe to quote generator expressions though.
