Openpose: CMake fails to download Caffe [Ubuntu]

[lgenzelis]

Issue Summary

After pressing "Configure" in CMake (leaving all options by default, except for BUILD_PYTHON), the process fails with error
Caffe will be downloaded from source now. NOTE: This process might take several minutes depending on your internet connection. fatal: not a git repository (or any of the parent directories): .git

The error is easy to solve. You need to go to the folder 3rdparty inside the cloned openpose folder, and type the command:
$ git clone https://github.com/CMU-Perceptual-Computing-Lab/caffe.git

Afterwards, pressing Configure again in CMake gives no error.

Still, I guess the default method should work, so I wanted to give the heads-up (as well as the workaround) here.

Type of Issue

• Compilation/installation error

Another solution is run git submodule update --init —recursive. It will also download pybind11.
