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.

run-cmake@v10 runs CMake with CMakePresets.json

The run-cmake action runs CMake on GitHub workflows leveraging CMakePresets.json. Note that usage of CMakePresets.json is required.

Good companions are the run-vcpkg action and the get-cmake action.

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

annotations for CMake errors/warnings and for build (gcc/msvc/clang) errors/warnings are created inline in the changed source files the build run for, e.g.:
when necessary, it sets up the environment to build with the MSVC toolset.
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. The regex is customizable by the user.

The provided samples use GitHub hosted runners.

Good companions are the run-vcpkg action and the get-cmake action.

Quickstart with instructions

It is highly recommended to use:

a vcpkg.json manifest file to declaratively specify the dependencies.
the required CMakePresets.json file.
vcpkg as a submodule of your repository.

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

      # Install latest CMake and Ninja.
      - uses: lukka/get-cmake@latest
      # 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:
          # This is the default location of the directory containing vcpkg sources.
          # Change it to the right location if needed.
          # vcpkgDirectory: '${{ github.workspace }}/vcpkg'

          # If not using a submodule for vcpkg sources, this specifies which commit
          # id must be checkout from a Git repo.
          # Note: it must not be set if using a Git submodule for vcpkg.
          # vcpkgGitCommitId: '${{ matrix.vcpkgCommitId }}'

          # This is only needed if the command `vcpkg install` must run at this step.
          # Instead it is highly suggested to let `run-cmake` to run vcpkg later on
          # using the vcpkg.cmake toolchain. The default is `false`.
          # runVcpkgInstall: true

          # This is only needed if `runVpkgInstall` is `true`.
          # This glob expression used to locate the vcpkg.json and  use
          # its directory location as `working directory` when running `vcpkg install`.
          # Change it to match a single manifest file you want to use.
          # 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
          # `**/path/from/root/of/repo/to/vcpkg.json` to match the desired `vcpkg.json`.
          # vcpkgJsonGlob: '**/vcpkg.json'

          # This is the default path to the CMakeLists.txt along side the

          testPresetAdditionalArgs: "['--config Release']"

     #  [OPTIONAL] Define the vcpkg's triplet you want to enforce, otherwise the default one
    #  for the hosting system will be automatically choosen (x64 is the default on all
    #  platforms, e.g. `x64-osx`).
    #  VCPKG_DEFAULT_TRIPLET: ${{ matrix.triplet }}
    #
    #  [OPTIONAL] By default the action disables vcpkg's telemetry by defining VCPKG_DISABLE_METRICS.
    #  This behavior can be disabled by defining `VCPKG_ENABLE_METRICS` as follows.
    #  VCPKG_ENABLE_METRICS: 1
