I have to download all the things from this link
https://github.com/adujardin/zed-openpose
I download the openpose file, and I put in its examples/user_code/ the zed-openpose file that i downloaded I get stuck in the installation process
cd openpose
mkdir build
cmake .. # This can take a while
make -j8
sudo make install
When I type cmake , it gives me the Error in the title: WHY?
