Ah, so that means we're talking about this issue having come up due to expectations about object naming being somewhat "usual" (as opposed to CMake-configured naming), of an *external tool*, rather than due to uneasiness/issues detected within the CMake workflow itself. So, that means: - CMake handling likely *is* consistent (at least in regard to this aspect) - the external tool does not like it :) - a manual specific compiler flag setting was configured to fall back to previously "usual" object naming So, my thoughts on this are that it would be best to have the external tool offer an option to support custom object file naming patterns, since naming of internally generated object files may easily differ in various build systems. Manually adding a very specific /Fo option *can* be done, but: - this manual tweak might then cause incompatibilities with internal CMake assumptions (quite possibly there are CMake configuration variables/mechanisms to generically switch this naming pattern though) - it's extremely compiler-specific (read: not environment-generic) So, I would recommend going the "improve external tool support" route instead (or resort to figuring out CMake config mechanisms to generically switch object naming).
