How to make tensorflow lite available for the entire system

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?
