Using TDM-GCC from github actions

[franko]

I normally use TDM-GCC from an MSYS2 MINGW64 environment to produce release builds of my applications.

I prefer TDM-GCC over the GCC provided by MSYS2 because it produces nice executables that doesn't require additional shared libraries.

What I would like now is to be able to use TDM-GCC from a github workflow. Ideally I would need to install TDM-GCC in a specific path and then proceed to use it by adding its directory to the PATH.

The problem is I know no way to install TDM-GCC from a github action using commands. The only way I know with the setup graphics interface.

Is there a way to run the setup as a command ?

Otherwise any other idea to use TDM-GCC from github actions ?
