Как решить ошибку, которая выходит при установке opencv 3.1 на человечности 16.04?

Я попытался установить opencv 3.1 в человечности 16.04, потому что я должен сделать алгоритм в C++ с opencv, я выполнил шаги различных учебных руководств, но ни один не работал на меня, единственный, с которым я совершенствовался больше, является этим:

Но когда я добираюсь до шага cmake, я получаю эти ошибки,

который я не решаю, кто-то, у кого есть некоторая идея, как решить ее для установки ее или кто-то, у кого есть хорошее учебное руководство, за которым я могу следовать так, я могу установить opencv в человечности.
