Ok, thanks for the info. Can I expect this "IN" mode to be delivered in 2.6.5?

Is this the wanted > behaviour? If it is, how can I manage empty elements when I need them? The foreach command never even sees the empty arguments. By the time ${list} is evaluated the empty elements are gone. This is for language consistency. No one would want add_executable(myexe ${srcs}) to try to add "" as a source file if srcs has an empty element. In CMake HEAD from CVS there is an "IN" mode for foreach that supports explicitly named lists: set(my_list "a;b;;c;d") foreach(arg IN LISTS my_list) ... endforeach() For now you need to use the list() command. You can iterate over a range of the list size with foreach(arg RANGE ...). -Brad This email was sent to you by Thomson Reuters, the global news and information company.
