I'm trying to write some MESSAGE() wrappers like info(), warning(),<br>
fatal(), etc which may be a bit easier to use. But I failed to simulate the<br>
correct MESSAGE() behavior no matter I use MACRO or FUNCTION. For example:<br></div>
[snip]<br>

<br>
FUNCTION vs MACRO shouldn't make a difference in argument parsing AFAIK. The difference is primarily that FUNCTION creates a scope, while MACRO operates in the scope from which it is called.<br>
<br>
The behavior of MESSAGE seems to concatenate multiple arguments with no separators. So maybe you could do something like:<br>
<br>
set(msg "")<br>
foreach(part IN LISTS ARGN)<br>
set(msg "${msg}{$part}")<br>
endforeach()<br>
# ...do stuff with ${msg}<br></blockquote><div><br></div><div>This does not work either. For example:<br><br></div><div>$ cat CMakeLists.txt <br>cmake_minimum_required(VERSION 2.8)<br><br>FUNCTION(info_f)<br> set(msg "")<br>
foreach(part IN LISTS ARGN)<br> set(msg "${msg}${part}")<br> endforeach()<br> message("[info_f] ${msg}")<br>ENDFUNCTION()<br><br>MACRO(info_m)<br> set(msg "")<br> foreach(part IN LISTS ARGN)<br>
set(msg "${msg}${part}")<br> endforeach()<br> message("[info_m] ${msg}")<br>ENDMACRO()<br><br>message("foo;bar")<br>info_f("foo;bar")<br>info_m("foo;bar")<br>
</div><div>$ cmake .<br>foo;bar<br>[info_f] foobar<br>[info_m]<br>$ <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

(I like ARGN since it is 'unnamed positional arguments'. Since you have no named arguments, ARGV == ARGN, but generally speaking I can't think of why you'd ever need to use ARGV.)<br></blockquote><div><br>
</div><div>Good point. <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
