Subject: [CMake] macro/functions in ctest scripts

Hi,

I have a project where we use ctest/cdash but not cmake. I wanted to add a macro, but it looks like it doesn't support arguments correctly?
(differing from the documentation in 'ctest --help-command macro')

I tried to add this to the CTestTestfile.cmake:

macro(hello MESSAGE)
   message("${MESSAGE}")
endmacro(hello)
hello("Hello World")

This does not work (it gives a warning that the message command was called with wrong number of arguments). However, if I try to call just
hello() I get an error stating that I called the macro with the wrong number of arguments.. What am I doing wrong here? I found the same behaviour with functions.


Cheers,
Yngve

Hi,

>>macro(hello MESSAGE)
>>   message("${MESSAGE}")
>>endmacro(hello)
>>hello("Hello World")

You're expecting MESSAGE to be variable name but you call it with string value. So 
message("${MESSAGE}")
evaluates to
message("${Hello World}")
and this to
message("")
and cmake does not like calling it with empty string :)

Hi,

a neee - just ignore this - I need more sleep...

This indeed looks like a correct piece of code.
Moreover - it works perfectly with my ctest...
