Compile appleintelinfo.kext

I need this kext for ssdtprgen since my cpu doesn't have a known low frequency mode but I have 0 experience with xcode, I downloaded it and tried to use the product>build tab and other than a target error 10.11 instead of 10.14 on the project it said build succeeded but if I try to do the next step (fixing permissions) it doesn't see any file or directory, did I skip something? The .md just says to compile it, I'm no programmer so I might be skipping something really stupid.
