Summary:                    lists parsing is quite strange and not as documented
Description: 
Hi.

http://www.cmake.org/cmake/help/syntax.html
tells that lists are set like:
set(VAR a;b;c)
or
set(VAR a b c)


However, when using string literals this doesn't work anymore, e.g.
1) List items separated by semicolons
set(foo "1 1";"2 2";"3 3")
message(${foo})
foreach(ff IN LISTS foo)
        message("dd: ${ff}")
endforeach()

=> yields in:
1 1"2 2""3 3"
dd: 1 1
dd: "2 2"
dd: "3 3"


2) List items separated by spaces
set(foo "1 1" "2 2" "3 3")
message(${foo})
foreach(ff IN LISTS foo)
        message("dd: ${ff}")
endforeach()

=> yields in:
1 12 23 3
dd: 1 1
dd: 2 2
dd: 3 3


(2) Is obviously what one would expect in both cases.


Cheers,
Chris.
