dlib 설치 오류

안녕하세요. 

dlib 설치과정에서 오류가 발생하여 질문 드립니다(이전에 올라온 오류내용과는 다른 것 같아서요).

저 같은 경우에는 Visual Studio for C++가 설치되지 않았다고 메세지가 뜨고 있구요. 확인해보니 Visual Studio 2017이 설치되어 있습니다(Ver. 15.9.33). C++용은 별도로 있는 건가요?

그리고 sudo 명령을 써서 설치 해보려고도 했는데 저는 Sudo를 치면 이렇게 에러가 뜨네요;;

'sudo'은(는) 내부 또는 외부 명령, 실행할 수 있는 프로그램, 또는 배치 파일이 아닙니다.
