A lot of these errors are due to ssize_t being undefined. You can fix this by editing C:\Users\agust\Downloads\dlib-19.22\dlib\external\pybind11\include\pybind11/numpy.h
Find these lines of code near the top of the file after the #include statements:
#if defined(_MSC_VER)
# pragma warning(push)
# pragma warning(disable: 4127) // warning C4127: Conditional expression is constant
#endif
Change to:
#if defined(_MSC_VER)
# pragma warning(push)
# pragma warning(disable: 4127) // warning C4127: Conditional expression is constant
#include <BaseTsd.h>
typedef SSIZE_T ssize_t;
#endif
This will provide a definition for ssize_t and allow the compiler to continue I had this problem too. After the change above, dlib built with no issues.

To add on to @Horhe & @Dharman's answer above, do make sure that you download the dlib package from the github repository
https://github.com/davisking/dlib.git
After which, navigate to the numpy.h file (As with the above answer) and make the necessary changes to declare ssize_t.
Once that is done, while in the directory of the cloned dlib folder install dlib by typing:
python setup.py install
This is important as pip install dlib will download the package from elsewhere and the change made to numpy.h in your downloaded folder will not be accessed.
This should install dlib and you can go onto installing face_recognition smoothly by typing:
pip install face_recognition

Follow these steps:
- Go to https://github.com/datamagic2020/Install-dlib
- Clone the Repo
- Extract the zip file
- Open up the terminal as Administrator
- Then install the suitable wheel by typing:
pip install \PATH\TO\WHEEL\dlib-19.22.99-cp310-cp310-win_amd64.whland making the necessary changes
