Sem muito BLÁ BLÁ BLÁ, para compilar a biblioteca e o respectivo exemplo, efetue o download dos fontes utilizando o comando abaixo (git clone), então teremos todo o código-fonte do repositório GitHub em nosso equipamento de trabalho.

git clone https://github.com/intel/gna

Agora entre na pasta recém-criada novamente e use o comando cmake e make como no exemplo abaixo.

cmake .
