[CMake] Wrong behavior with 3.2.0-rc2

[Pere Mato Vila]

Using version 3.2.0-rc2 on the Mac OS X 10.10 with the make generator. The following example executes the custom to create A.txt and B.txt twice when building with make -jN

————————-
cmake_minimum_required(VERSION 2.8.8 FATAL_ERROR)
add_custom_target(Main ALL DEPENDS A.txt B.txt)
add_custom_command(OUTPUT A.txt B.txt
                   COMMAND touch A.txt
                   COMMAND touch B.txt)

————————-
$ make clean
$ make -j10
-- Configuring done
-- Generating done
-- Build files have been written to: /Users/mato/Development/ROOT/build.master/temp
[100%] [100%] Generating A.txt, B.txt
Generating A.txt, B.txt
[100%] Built target Main


This is not the case for version 3.1.3.
Cheers,


Pere
