compilation error "fatal error: stb_image.h: No such file or directory"

[martian17]

Being an absolute beginner in image processing in C, I ran the most intuitive command that I could come up with: make
However, that was met with the following error

$ make
cc -std=gnu99 -O3 qoibench.c -o qoibench -lpng
qoibench.c:41:10: fatal error: stb_image.h: No such file or directory
   41 | #include "stb_image.h"
      |          ^~~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:14: qoibench] Error 1

Does this mean that I need to copy over stb_image.h from somewhere else? or do I need to rewrite the source to point the header include to somewhere else?
I hope I'm not alone on this.
Also, I think there should be an instruction on how to compile on the main README page for beginners like me.

See https://github.com/phoboslab/qoi/blob/master/qoiconv.c#L5. Essentially you just need to have those downloaded h files in the same folder. Alternatively you can add an extra CC flag with the -I arg to tell it where it is on your system (if you use a package manager to install that lib).

I ended up cloning https://github.com/nothings/stb.git into a different directory, and re-writing each c files to point to that directory.
That worked, but I'll try editing the Makefile to add the -l arg from next time.
Thank you for the advice!
