I would love to get vcpkg installed deps to be cached. It takes forever to build OpenSSL for example, and I'd love to not do this every time I build.

Did you find a solution? I am in the process of adding vcpkg to my builds and wondering how to avoid rebuilding deps over and over

I actually never looked into this, but maybe it could work with vcpkg, it's just that no-one ever tried or wrote doc for it. This cache system looks generic, you need to provide a key, a path and a 'rebuild-thing' values.

https://github.com/actions/cache/blob/main/examples.md#python---pip is an example for python.

I don't know where vcpkg puts its output files.

Can't we use something like this:

    - name: Cache
      uses: actions/cache@v2
      with:
        path: |
          ~/vcpkg
          ./build/vcpkg_installed
          ${{ env.HOME }}/.cache/vcpkg/archives
          ${{ env.XDG_CACHE_HOME }}/vcpkg/archives
          ${{ env.LOCALAPPDATA }}\vcpkg\archives
          ${{ env.APPDATA }}\vcpkg\archives
        key: ${{ runner.os }}-${{ env.BUILD_TYPE }}-${{ hashFiles('**/CMakeLists.txt') }}-${{ hashFiles('./vcpkg.json')}}
        restore-keys: |
          ${{ runner.os }}-${{ env.BUILD_TYPE }}

Assuming vcpkg is installed in ~/vcpkg.

The archives paths are based on these: https://github.com/microsoft/vcpkg/blob/master/docs/specifications/binarycaching.md#backend-1-file-based-archives https://vcpkg.io/en/docs/users/binarycaching.html#configuration

This issue is open still. vcpkg build the dependencies again and again.
