MinGW Compiling code using Opus using libraries

Hello,

I am looking at using libraries but I have already given a few shots... Let say I want to compile this standalone Opus use file: https://pastebin.com/L5P2cyZS

I have libraries available here? https://archive.mozilla.org/pub/opus/win32/opusfile-v0.9-win32.zip

If I do mingw32-g++ main.cpp -L "folderWhereIUnarchiveThePreviousFile" I always get:

undefined reference to `opus_get_version_string'

and others... (I tried this several times in the past weeks...)

Any ideas please?

Note that main.cpp is the code from the pastebin.
I know that g++ don't get the good libraries but I don't know how to solve it...
Am I trying to link not the good libs?

It seems that there isn't any available Windows artifact here: https://github.com/xiph/opus-tools/issues/43

Could we have precise instructions for Windows using MinGW and not Microsoft Visual please? (cf README.md 0) Set up a development environment)

Start with the README's “Set up a development environment” section, the linked main.cpp paste, and the opusfile-v0.9-win32.zip contents. Reproduce the reported mingw32-g++ command and determine the documented MinGW linking steps. Done means the README includes precise Windows MinGW instructions that build the standalone example without undefined references.
