How to make a path available for the entire system in Ubuntu

My tflite directory is as follows:

/home/me/tensorflow_src/tensorflow/lite/

However, I fail to import it in my C++ project:

#include "tensorflow/lite/interpreter.h" // getting a not found error

How can I add resolve this error? My assumption is that I'd need to add the tflite to my bash to make it available for all of my projects. How can I add tflite to the bash file? This is my CMAKE file:

cmake_minimum_required(VERSION 3.22)
project(mediafile_device_crossverification)

set(CMAKE_CXX_STANDARD 17)

set(OpenCV FOUND 1)
find_package(OpenCV REQUIRED)
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_executable(mediafile_device_crossverification main.cpp src/VideoProcessing.cpp src/VideoProcessing.h)
