Help installing the ADIS16470 C++ library

I am currently trying to install the ADIS16470 library for C++. I downloaded the zip, made sure all instances of VS Code were closed, extracted to the correct place for windows, and installed it offline. However, when I try to build the code I get the error message “fatal error: ADIS16470_IMU.h: No such file in directory”. And it points toward my include statement. I have tried reinstalling it but no luck. Is there something I am doing wrong or something I am missing?

This is the link showing how to install the library.

The location to extract on that page is for last year. Here’s the correct location: https://docs.wpilib.org/en/latest/docs/software/wpilib-overview/3rd-party-libraries.html#the-mechanism-c-java
