Hello,

as CMake apparently doesn't make a big difference between lists and
strings internally, you can simply replace all spaces with ';' in a
string to get a list.

The following snippet will send the strings "1", "2" and "3" to the
messages console, each of them on its own line:

  SET(FOO "1 2 3")
  STRING(REPLACE " " ";" FOO_LIST "${FOO}")
  FOREACH(item ${FOO_LIST})
    MESSAGE(${item})
  ENDFOREACH(item ${FOO_LIST})

If your string may contain spaces as payload data you will have to be
more careful when doing the replacement, though...
