This action downloads and installs the mold linker as the default linker.

Just add the following line to the steps: list in your GitHub Action YAML file:

- uses: rui314/setup-mold@v1

You can optionally pass parameters to the action as follows:

- uses: rui314/setup-mold@v1
  with:
    mold-version: 1.1.1
    make-default: false

mold-version specifies the mold version to install. By default, the most recent version will be installed.

If make-default: false is specified, mold will still be installed as /usr/local/bin/mold but it won't replace the default linker. If you choose not to install mold as the default linker, you need to pass an appropriate option such as -fuse-ld=mold to the compiler to use mold.
