Cannot include <stdint.h> , Eclipse ESP-IDF

[Hailwiz9]

Hello,

I have used arduino before and I can be said to be a beginner in terms of C, C++
I wanted to learn more in-depth coding by diving into the ESP-IDF environment, I'm using Eclipse IDE,
I'm trying to convert the DMD32 library which was written for arduino to be used in ESP-IDF but got stuck at some type declarations.
I can't seem to include "uint8_t" into the C type Header file,
I've figured if I included <stdint.h> it would work but the IDE can't seem to find the library.

I don't know if this problem is with the Eclipse IDE or I'm doing something wrong with file types or such, tried to find Path options in Eclipse IDE but can't seem to find it.

Example code is given below, and the Eclipse IDE response can be seen in the attachment picture

Thanks for your help,
