python cmake dlib

Dlib documentation says:

We should also make a special note of the problems associated with using precompiled C++ libraries with Visual Studio. The TLDR is that you should not use precompiled libraries (i.e. .lib files) with Visual Studio unless you really know what you are doing. This is not a dlib limitation. It has nothing to do with dlib. It's just how Visual Studio works. Please do not ask me about it. If you want to understand this you should read the Visual Studio documentation and this excellent overview in particular.

With that beeing said, it's likely they don't ship precompiled library with their installers, and it order to use it on windows you have to compile it yourself, and to compile it you need Visual Studio (mingw or clang wont work).

If you dont mind installing another instance of python in your system, you can use conda to get precompiled dlib.
