Important: run-vcpkg@v11 requirements

run-vcpkg@v11 requires vcpkg more recent than 2023-03-29 (e.g. commit id 5b1214315250939257ef5d62ecdcbca18cf4fb1c).

Quickstart with a C++ project template

Take a look at this C++ project template that applies all the following instructions, but also shows how to create a pure workflow without using special GitHub action that you cannot run locally on your development machine, but directly using the tools (CMake, Ninja, vcpkg, C++ compilers) you already use daily.

The run-vcpkg@v11 action

The run-vcpkg@v11 action setups (and optionally runs) vcpkg to install the packages specified in the vcpkg.json manifest file. It leverages the vcpkg's Binary Caching backed to GitHub Action cache, delegating cache and key management to vpckg.

Special features which provide added value over a pure workflow are:

automatic caching leveraging vcpkg's ability to store its Binary Caching artifacts onto the GitHub Action cache so that packages are built only once and reused in subsequent workflow runs. The user can customize the behavior by setting the environment variable VCPKG_BINARY_SOURCES before vcpkg runs.
set the workflow variables ACTIONS_CACHE_URL and ACTIONS_RUNTIME_TOKEN to let users easily running vcpkg in a run step such as - run: vcpkg install or - run: vcpkg integrate install without forcing the users to set the variables manually.
automatic dump of log files created by CMake (e.g., CMakeOutput.log) and vcpkg. The content of those files flow into the workflow output log. Customizable by the user by setting the input logCollectionRegExps.
automatic parsing of CMake, vcpkg and gcc, clang, msvc errors, reporting them contextually in the workflow summary by means of annotations.
although disabled by default (see input doNotCache), run-vcpkg can cache vcpkg's executable and data files to speed up subsequent workflow runs. Since bootstrapping vcpkg already downloads a prebuilt binary saving the time to build vcpkg, this form of caching is useful only when the prebuilt executable is not served as it happens for the ARM platform. Note this cache does not contain the libraries built by vcpkg, which is instead managed by vcpkg itself.

The provided samples use GitHub hosted runners.

Good companions are the run-cmake and the get-cmake actions.

Quickstart with instructions

It is highly recommended to use:

vcpkg as a submodule.
a vcpkg.json manifest file to declaratively specify the dependencies.
a CMakePresets.json file.

    steps:
      #-uses: actions/cache@v3   <===== YOU DO NOT NEED THIS!

      # Install latest CMake and Ninja.

      # Or pin to a specific CMake version:
      # lukka/get-cmake@v3.27

      # Setup vcpkg: ensures vcpkg is downloaded and built.
      # Since vcpkg.json is being used later on to install the packages
      # when `run-cmake` runs, no packages are installed at this time
      # (and vcpkg does not run).
      - name: Setup anew (or from cache) vcpkg (and does not build any package)
        uses: lukka/run-vcpkg@v11 # Always specify the specific _version_ of the
                                  # action you need, `v11` in this case to stay up
                                  # to date with fixes on the v11 branch.
        #with:

          # Change it to the right location if needed.
          # vcpkgDirectory: '${{ github.workspace }}/vcpkg'

          # If not using a Git submodule for vcpkg sources, this input
          # specifies which commit id to checkout from a Git repo.
          # Notes: 
          # - it must _not_ be set if using a Git submodule for vcpkg.
          # - if not provided, the `vcpkgConfigurationJsonGlob` or `vcpkgJsonGlob`
          #   are being used to locate either a vcpkg-configuration.json or vcpkg.json

          # This is only needed if the command `vcpkg install` must run at this step.

          # using the vcpkg.cmake toolchain. The default is `false`.

          # Note: do not use `${{ github.context }}` to compose the value as it
          # contains backslashes that would be misinterpreted. Instead
          # compose a value relative to the root of the repository using

Best practices

Use vcpkg as a submodule of your repository

It is highly suggested to pin the specific version of vcpkg you want to use to keep a consistent development experience between local and remote build environments. This is accomplished by using vcpkg as submodule of your Git repository; this way the version of vcpkg used is implied by the commit id specified by the submodule for vcpkg.

Use vcpkg's vcpkg.json file to specify the dependencies

The vcpkg.json is a manifest file that declaratively specifies the dependencies to be installed. The file is being used automatically by running CMake (e.g. by using run-cmake) when:

starting CMake with the vcpkg.cmake toolchain file.
the root CMake source directory contains a vcpkg.json file.

Or it can also be used by invoking vcpkg install in a directory where vcpkg.json is located (e.g., input runVcpkgInstall : true).

When conditions are satisfied, the toolchain execution starts vcpkg to install the packages declared in the manifest file.

Putting this manifest-like file under source control is highly recommended as this helps to run vcpkg the same exact way locally and remotely on the build servers. The dependencies specified in the vcpkg.json file are installed when CMake runs (i.e. at run-cmake execution time).
