Building 1.3.0 beta issue

Hello,
When trying to build the beta version, I get the following errors

Jean-Marc@DESKTOP-SKLA4BG MSYS ~/siril

$ meson _build
-bash: meson: command not found

and if I try

Jean-Marc@DESKTOP-SKLA4BG MSYS ~/siril
$ D:/msys64/mingw64/bin/meson.exe _build

Did you follow this step by step page?

https://siril.readthedocs.io/en/latest/installation/windows.html#building-on-windows-with-msys2

I just followed this page step by step and I got the error

Jean-Marc@DESKTOP-SKLA4BG MSYS ~/siril
$ git submodule update --init

Jean-Marc@DESKTOP-SKLA4BG MSYS ~/siril
$ meson setup _build --buildtype release
-bash: meson: command not found

Looks like meson is not in the PATH

Sorry, I did a mistake. I was launching Msys2.exe instead of mingw64.exe
