Issues with headers for DWM3001CDK-demo-firmware

[Sebastian-Pirela]

I downloaded the contents of this GitHub repository and used VScode but I keep having problems with missing file headers such as "FreeRTOS.h", "compiler_abstraction.h", "task.h", "queue.h", "nrf_gpio.h" etc. So I was wondering if this is an actual issue or it is just my ignorance and I would kindly ask someone for some guidance.
