Adding library from GitHub

I’m a beginner and trying to add a library from GitHub to my project.

I have added the following code in my platformio.ini file:

lib_deps = 
    ;   nrf24L01
    ;   E22

the library for the nrf24L01 works well but after I add in the E22 library using the GitHub link and rebuild, the following error occurs:

If I’m not mistaken, the SoftwareSerial.h is an inbuilt library for the Arduino framework. Am I adding the GitHub library wrongly? If yes, please guide me on how to add the library correctly.

Ps: I can’t find the library by searching it within the Platformio and thus I’m adding it using the GitHub link.

Since the library inclusion is guarded by a macro

PlatformIO’s library dependency finder (LDF) needs to be set to a more aggressive mode to recognize the dependency. As per docs, try adding

lib_ldf_mode = chain+

to the platformio.ini and retry compilation.

Did you mean like this?

but the problem still remains

I cannot reproduce the issue when using the source code

#include <Arduino.h>
#include <RF24.h>
#include <LoRa_E22.h>

void setup() {

void loop() {

and platformio.ini

platform = atmelavr
board = uno
framework = arduino
lib_deps = 
    ;   nrf24L01
    ;   E22
lib_ldf_mode = chain+

Make sure to at least include the library’s header in your code.
