Original intention was to install dlib dep for https://github.com/cubiq/ComfyUI_FaceAnalysis. Even though both cmake and MSVC 14 with VS 2022 build tool (17.9.7) were installed, when doign pip install dlib under ComfyUI_FaceAnalysis venv, it complained that cmake was not available.
So tried to build it from latest dlib repo. Took such a long time debugging the process:
  - initially build failed with ValueError: path 'dlib/CMakeLists.txt/' cannot end with '/'. Found https://github.com/davisking/dlib/issues/2668 which led to https://github.com/davisking/dlib/issues/2480#issuecomment-1003647257. Apparently the build needs to be in the same drive as where Python is located (I had it in C:), even though the build was initiated from a venv (in D:).
  - then the build couldn't locate cudnn, as cmake needs these cmake specific paths to point to the cudnn directories - https://stackoverflow.com/questions/78276120/dlib-fails-to-install-with-cuda-says-i-am-missing-cudnn
  - build still failed as cuda wasn't compatible
