O Opencv requer muitas dependências para serem construídas a partir de fontes. A maneira mais fácil seria instalar todas as dependências de compilação usando este comando:
sudo apt-get build-dep opencv
E reinicie a configuração cmake .
Durante a instalação do OpenCV, recebo o seguinte erro:

sudo apt-get build-dep opencv
E reinicie a configuração cmake .
