This is the simplest solution for the upcoming 3.1 release because it just restores behavior to what 3.0 does. I've done it here: Ninja: Limit custom command side-effects to build folder http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=de8e534b > simply to solve a problem that is, if some projects do *not* > properly use CMake (GENERATED property, adding dependencies > properly on commands/target that generate the said input > files...etc) we need to do this to keep them working. This is not about supporting projects that do it wrong. Ninja wants to know not just that a file is generated, but also *which* custom command generates it. We have no interface for specifying side-effect outputs whose timestamps do not need to be newer than the inputs. That is what this issue is about: Add explicit specification of custom command side effect outputs http://www.cmake.org/Bug/view.php?id=14963 The reason is that CMake was designed long before Ninja existed, and all the other build systems not only do not need this information, but have no place to put it even if we did have it.
