CMake Action

Configure, build, and test your CMake project using GitHub Actions. This action simplifies the workflow for configuring the build environment of a CMake project. It can also be optionally specified to build a CMake project using the cmake --build command and test it using the ctest command.

Features

• Configures a CMake project using the cmake command.
• Optionally builds a CMake project using the cmake --build command.
• Optionally tests a CMake project using the ctest command.
• Auto-detects and installs required dependencies.
• Supports specifying multiple CMake options directly from the action inputs.

Usage

For more information, refer to action.yml and the GitHub Actions guide.

c-compiler	String	The preferred executable for compiling C language files. It appends the CMake configuration arguments with -D CMAKE_C_COMPILER=[val].
cxx-compiler	String	The preferred executable for compiling C++ language files. It appends the CMake configuration arguments with -D CMAKE_CXX_COMPILER=[val].
c-flags	Multiple strings	Additional flags to pass when compiling C language files. It appends the CMake configuration arguments with -D CMAKE_C_FLAGS=[vals].
cxx-flags	Multiple strings	Additional flags to pass when compiling C++ language files. It appends the CMake configuration arguments with -D CMAKE_CXX_FLAGS=[vals].
options	Multiple strings	Additional options to pass during the CMake configuration. It appends the CMake configuration arguments with each of -D [val].
args	Multiple strings	Additional arguments to pass during the CMake configuration.
run-build	true or false	If enabled, it builds the project using CMake. It defaults to false.
build-args	Multiple strings	Additional arguments to pass during the CMake build.
run-test	true or false	If enabled, it runs testing using CTest. It defaults to false.
test-args	Multiple strings	Additional arguments to pass during the CTest run.

Examples

name: Build
on:
  push:
jobs:
  build-project:
    name: Build Project
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4.1.1

      - name: Configure Project
        uses: threeal/cmake-action@v1.3.0

      - name: Build Project
        runs: cmake --build build

      - name: Test Project
        runs: ctest --test-dir build

Note: You can replace v1.3.0 with any version you prefer. See this.

Configure, Build, and Test in the Same Step

- name: Configure, Build, and Test Project
  uses: threeal/cmake-action@v1.3.0
  with:
    run-build: true
    run-test: true

Specify the Source and Build Directories

- name: Configure Project
  uses: threeal/cmake-action@v1.3.0
  with:
    source-dir: submodules
    build-dir: submodules/out

Using Ninja as the Generator and Clang as the Compiler

- name: Configure Project
  uses: threeal/cmake-action@v1.3.0
  with:
    generator: Ninja
    c-compiler: clang
    cxx-compiler: clang++
