I am not able to install dlib on my computer. It gives me this error, but no other posts have helped me. I have been searching for a few hours now but to no avail. I am not familiar with the pip command, so this error does not tell me any meaningful information. Can someone who is more experienced please tell me why this is not working? I have already tried reinstalling Microsoft Visual Studio C++ 2015, but that did not work. Installing CMake did not work either. Can someone please help me fix this?

WARNING: You are using pip version 21.1.2; however, version 21.3.1 is available.
You should consider upgrading via the 'C:\Users\danie\Desktop\pythonProject\venv\Scripts\python.exe -m pip install --upgrade pip' command.
download cmake executable file on your pc, install it and install cmake build tools for c++ from visual studio build tools. After installing cmake with visual studio build tools, you need to download dlib wheel file from this github repo: https://github.com/Tobyyosoba777/Computer-Vision-OpenCv-Python-/tree/main/Libraries
download: dlib-19.22.99-cp39-cp39-win_amd64.whl
and download: dlib-19.22.99.win-amd64-py3.9.exe
install the .exe file on your pc, restart it(not necessary) and open the current directory of the downloaded .whl file where it is saved on your pc in your python/anaconda terminal/ cmd
for example:
C:\Users\USER->cd desktop "if you downloaded the file to your desktop" this command will move you to the current directory of the .whl file
then input: "pip install dlib-19.22.99-cp39-cp39-win_amd64.whl"
that should work
