WARNING: You are using pip version 20.2.3; however, version 21.1.2 is available.
You should consider upgrading via the 'D:\Install Drive\python.exe -m pip install --upgrade pip' command.

Notice that in the output that "CMake must be installed to build the following extensions: dlib". So install CMake first and only then try to install dlib. If CMake is installed, try updating your pip version to 21.1.2 via "D:\Install Drive\python.exe -m pip install --upgrade pip".

It requires cmake must be installed before installing dlib. Do execute in the following order.
pip install cmake
pip install dlib
This will fix the issue.

Have you try this steps? Face-recognition on windows
Officially this package is not supporting windows but this steps might be help you.
Also the another way is you can download it's environment with virtual box on windows system. From here pre-configured VM
I guess it will help you. Thank you

Why don't you adopt deepface? It is more lightweight and it covers Keras based facial recognition models. In other words, it is easier to install and run.
#!pip install deepface
from deepface import DeepFace
models = ["VGG-Face", "Facenet", "OpenFace", "DeepFace", "DeepID"]
res = DeepFace.verify("img1.jpg", "img2.jpg", model_name = models[0])

How to upgrade dlib python package in Windows python 3.6

I am using python3.6 and have installed dlib using its wheel file dlib-19.8.1-cp36-cp36m-win_amd64.whl on windows 10 x64. This wheel file installed dlib but the version installed is 19.8.1. I want to upgrade it to 19.20 which is the latest version. To do this, I am using upgrade command python -m pip install dlib --upgrade but this gives me below error:

Have you tried installing python 3.7 instead of 3.8? I just ran into a similar error with 3.8 but no problems with 3.7 (and upgraded pip and setuptools). Seems like 3.8. will only work with pythonnet version >= 2.5

Looks like you are getting the error when you are installing dlib which is a prerequisite for face recognition. Since you are trying to install it on windows, there are certain prerequisites which you must ensure.
1. You will need to download cmake and install it and ensure the path is set in your environment variables.
2. You will need to have VS 2015/2017 installed.
I have not been able to get dlib working with VS2019 so far and I am not sure if it works well, hence use either 2015/2017.
Then download dlib from their github link and manually build the library instead of doing pip install.
Once dlib is installed you will then be able to install face-recognition using pip
