the tools/deps.sh script does not clone this repo automatically since for native compilation it is not needed.
Note2: if you get an error like the following one for "make binaries"
```sh
/usr/bin/ld: cannot find -lOpenCL
```
the main reason is probably that the 32-bit version of libOpenCL.so was not found.
A possible solution is to just symbolic link it (if the 32-bit version of libOpenCL.so.1 exists), for example:
```sh
sudo ln -s /usr/lib/i386-linux-gnu/libOpenCL.so.1 /usr/lib/i386-linux-gnu/libOpenCL.so
```
