Hello!

This error indicates that the dlib library was not found in the machine.
Recently this crate has changed it's behaviour to not include the entire download and installation of dlib by default, and also the feature flag to enable this was modified to "build-native"

The "build-native" flag will download and make a local install for dlib, but in case you dont wish this, do look for instructions on how to build and use it in Windows globally.

I did a quick test in my Win11 machine, and when changing the feature flag's name to "build-native", seems like it was built correctly.

There seems to be some bugs in the code however, i'll take a look at them shortly..

Do let us know if the problem persist!

Hi, it seems that the system library dlib you installed has not found by our build.rs. Could you register an environment variable DEP_DLIB_INCLUDE to your dlib path? It's likely be a __YOUR_LIBRARY_PATH__/dlib-19.24 if you downloaded it from the official homepage.
