note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for dlib
ERROR: Could not build wheels for dlib, which is required to install pyproject.toml-based projects
I do not understand this error, cmake
is already installed.
import sys
print(sys.version)

it seems error is coming from cmake installation , when trying cmake --version command in cmd , the command is not recognized by compiler .
C:\Users\Rayane_2>cmake --version
'cmake' is not recognized as an internal or external command,
operable program or batch file.
I solved the problem , those are the steps:
python --version
or python3 --version
pip --version
or pip3 --version
cmake --version
I installed cmake again using official website https://cmake.org/download/
Update pip and setuptools. Older versions might have compatibility issues with dlib. Use the following commands to update:
pip install --upgrade pip
pip install --upgrade setuptools
Install Visual Studio build tools. If you're using Windows, you'll need Visual Studio and C++ build tools. You can download them from the Visual Studio website: https://visualstudio.microsoft.com/visual-cpp-build-tools/
Go to the Visual Studio downloads page at https://visualstudio.microsoft.com/downloads/
Under the "All downloads" section, find "Tools for Visual Studio 2019". Click on "See all downloads".
In the opened page, find "Build Tools for Visual Studio 2019" and click the "Download" button next to it.
Run the downloaded installer. This opens the Visual Studio Installer.
In the installer, under "Workloads", select "C++ build tools".
Make sure to include at least the following components on the right:
Click "Install" to start the installation.
Once done , install again from cmd / jupyter cell : pip install dlib
Import using : import dlib
