Maybe related to this bug fix ?? http://public.kitware.com/Bug/view.php?id=9963 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=269a4b876a34483c5cb664499dc6b1634fa453ff We prepend "echo >nul && " to every command line that begins with a double quote to fix the bug... Which should be a no-op. But not if it pushes a long command line over the limit. I wonder if it goes away if you use a build tree with a 13-character-shorter path name. (Or if it would appear in the previous CMake if you use a build tree with a 13-character-longer path name.) Or if it's actually something else. I'm just guessing here... Could you do a simple test and see if it goes away if you use a shorter (by 13 or more characters) name for your build tree?
