I've spent two days trying to install dlib using pip on windows 11 for python 3.10.5 without any success.
I have installed C++ development tools using Visual Studio 2019 installer and cl.exe is in the PATH.
I have also installed Cmake from cmake.org and it's binary is in the path.
I have also installed cmake module for python using pip. But every time I try to install dlib it gives me the following error. I have also tried installing using python setup.py install. dlib version download from PyPi repository is 19.24.2.
