Start with the reported pip install face_recognition command and the dlib setup.py build output. Review the CMake configuration and the missing cl compiler error in the Windows 10, 32-bit Python 3.6 environment. Done means the package installs successfully in the reported setup or the project clearly documents the supported installation path.
