Is this a known thing, or a bug (I'm using cmake 3.1.0):
I create this CMakeLists.txt:
cmake_minimum_required(VERSION 3.1.0)
project(ArgTest)
function(FOO one two)
message(STATUS "extra args are ${ARGN}")
message(STATUS "third arg is ${ARGV2}")
endfunction()
function(BAR one)
FOO(${one} TWO)
message(STATUS "do something with ${ARGN}")
endfunction()
BAR(ONE N1 N2 N3 N4)
Note how I invoke BAR() with 5 arguments, but BAR invokes FOO with only
two arguments. I would expect that the third argument ${ARGV3} would be
empty in function FOO.
However, when I run cmake on this file it shows:
-- extra args are
-- third arg is N2
-- do something with N1;N2;N3;N4
So the ARGN for function FOO is correct (nothing there) but FOO has
"inherited" the extra ARGVx arguments beyond the first two, that I
passed to function BAR!
That's rather unexpected. Bug or feature?
