Fails when building executable for windows on a mac

[csikosjanos]

Thank you for this great tool. It makes life much easier.

I'm having a github actions that runs on a mac (runner.os == 'MacOS') and trying to build a windows executable (inputs.build-platform is 'windows/amd64').

The build works if it run locally although it fails in GHA runner.

Error context:

Run wails build --platform windows/amd64 -webview2 download -o my-project-name
Wails CLI v2.7.1

It does make sense. We don't have such a path when building a windows app.

Would it help if the condition in the Add macOS perms checks the inputs.build-platform instead of runner.os, or that would cause even more chaos?

    - name: Add macOS perms
      if: inputs.build == 'true' && runner.os == 'macOS'
      working-directory: ${{ inputs.app-working-directory }}
      run: chmod +x build/bin/*/Contents/MacOS/*
      shell: bash

to

    - name: Add macOS perms
      if: inputs.build == 'true' && startsWith(inputs.build-platform, 'darwin')
      working-directory: ${{ inputs.app-working-directory }}
      run: chmod +x build/bin/*/Contents/MacOS/*
      shell: bash

Many thanks for the insight and the help.

That would be better; this is an excellent idea; there are 10 uses of runner.os for Macos, some are host-based, and some are build-based. If I convert all build statements to use the build platform, with more chaos... the action would be better for cross compiling.
