Summary:                    enhance if() to support list
Description: 
Currently, to test if a list contains an element, the following pattern must be
used:
list (FIND my_list ${my_item} is_found)
if (NOT ${is_found} EQUAL -1)
   # item exists in list
endif ()

I suggest to extend if() syntax to support test of existence of an item in a
list:
if (<variable|string> IN <list>)

So, the previous test becomes:
if (my_item IN my_list)
  ...
endif ()
