Core setup help

while running cmake im running in to an issue after looking online and im not experienced with a few of these programs. I am unable to find a solution to this problem. and i went through and re setup all the programs to make sure i did everything correct following the requirements and now on the core installation. Feel free to message me if you have some time to help me out and hopefully create a solution that others can use on this thread. my discord user is kylezzz101#3942. if you need more information ill post the full log on pastebin.
