I think you meant "MKV CUE maker" or a similar tool, but I'm assuming you are referring to a software tool called "MKV CUE maker" or a similar one, specifically "mkv cue maker" doesn't exist, but there are tools like mkvpropedit and cue maker or programs like HandBrake , MakeMKV which create MKV files. However a more likely candidate for what you are referring to would be mkvmerge A part of the MKVToolNix package.
