Hi, I’ve stumbled over following behavior and now I’m searching for the rules, that explains that behavior:
test.cmake: macro(check_argn) message("in macro check_argn ARGN: ${ARGN}") if(ARGN) foreach(item IN LISTS ARGN) message("ARG: ${item}") endforeach(item) message("ARGN: ${ARGN}") endif() endmacro() function(f1 a) message("in function ARGN: ${ARGN}") check_argn() endfunction() f1(1) f1(1 2) This will yield the following output: $ cmake -P ./test.cmake in function ARGN: in macro check_argn ARGN: in function ARGN: 2 in macro check_argn ARGN: ARG: 2 ARGN: I would expect ARGN to behave exactly the same in the macro, as in the function, but apparently there is a difference. Can someone of you explain that to me?
