You must use Visual Studio to build a python extension on windows. If you
are getting this error it means you have not installed Visual C++. Note
that there are many flavors of Visual Studio, like Visual Studio for C#
development. You need to install Visual Studio for C++.

I faced the same issue so what I did I preferred youtube and watched in one video I am sharing the link to that video that might help
Video Link
for short I download visual studio downloader and installed C++ dependencies and first I installed CMake then dlib because dlib takes C++ dependencies then I choose the specified version of dlib and it worked fine but if still, it doesn't work so again
I would recommend using conda environment in conda it works properly but make sure to use basic dependencies (C++ and Cmake)
