Mas quando chego ao passo cmake, recebo esses erros,

que eu não resolvo, alguém que tenha alguma ideia de como resolvê-lo para instalá-lo ou alguém que tenha um bom tutorial que eu possa seguir para que eu possa instalar o opencv no ubuntu por favor.
No seu terminal cd para sua pasta de compilação. Execute ccmake .. , use as teclas de seta para navegar entre as páginas, na última página, a seta para baixo até WITH_QT , digite para desativá-lo. Pressione c para configurar e g para gerar.
