Homebrew app Can't compile homebrew (hidKeysDown)

[ThatBenderGuy]

I have recently installed Ubuntu and was setting up my development environment for DevKitPro. My project is to update a dead homebrew for personal use. I have installed all the switch libraries using dkp-pacman, and when I run make in the project's directory I get a bunch of errors but they all stem from the error:

source/main.c:501:33: error: 'CONTROLLER_P1_AUTO' undeclared (first use in this function) u64 kDown = hidKeysDown(CONTROLLER_P1_AUTO);

I have not programmed in C much but I assume due to changes in libraries since this the last time the homebrew was updated that CONTROLLER_P1_AUTO is deprecated now but I have no clue how to figure out what replaced it. The project does use SDL2 but it's not used in the main.c file (which is where this compile error is occuring). Any suggestions or ideas? I'm new to switch homebrew development but I really wanted to update this app because it's useful.

EDIT:
I also noticed I get these compile errors

warning: implicit declaration of function 'hidScanInput' [-Wimplicit-function-declaration]
warning: implicit declaration of function 'hidKeysDown' [-Wimplicit-function-declaration]

It is not a depreciate but a removed API. Read libnx changelog to find what to use instead.
