I know this is quite old but...

I was searching around Github when I found this magnificent piece of art. So I downloaded it, took a look at the readme, did what it told me to do and all was well. Until I got a make error, it stems from the part of the make command that looks for a make file in /lib/modules/.../build, why is it looking for a make file in there and how do I fix this.

Error:
make -C /lib/modules/5.6.16-1-MANJARO/build M=/home/thesc/Downloads/kernelroll.mp3
make[1]: Entering directory '/usr/lib/modules/5.6.16-1-MANJARO/build'
