Install MinGW

Set up MinGW-w64

This GitHub action sets up MinGW-w64 in your workflow run.

Use it in your workflow like this:

- name: Set up MinGW
  uses: egor-tensin/setup-mingw@v2
  with:
    platform: x64

x64 is the default value for the platform parameter and can be omitted. Use x86 if you want to build 32-bit binaries.
Set the cygwin parameter to 1 to set up MinGW inside an existing Cygwin installation (see my other action for setting up Cygwin itself).
cc and c++ executables are set up, pointing to the *-gcc and *-g++ executables. Disable this by setting the cc parameter to 0.

Input	Value	Default	Description
platform	x64	✓	Install the x86_64 toolchain.
	any		Install the i686 toolchain.
cygwin	any	✓	Install native binaries.
	1		Install Cygwin packages.

	any		Disable the static-linking workaround.

	any		Don't set up `cc`/`c++`.
