Now execute ``bii cpp:build`` to build the project. **Note** that this can take a while, until it downloads and builds OpenCV. However, this is downloaded just once in your machine in your "user/.biicode" folder. If the OpenCV installation process fails, you might simply go there, delete OpenCV files inside "user/.biicode" and repeat.
