Using C++ Build Systems with integrated development environments (IDEs)

When working with C++ projects, having a reliable and efficient build system is crucial. Build systems automate the process of compiling source code files into executable programs, making development workflows smoother and more organized.

Many Integrated Development Environments (IDEs) provide built-in support for popular build systems in the C++ ecosystem. In this article, we will explore how to leverage these build systems within IDEs to streamline your C++ development process.

1. CMake

CMake is a widely-used cross-platform build system generator that enables developers to define build configurations using a human-readable syntax. It generates build files suitable for various build systems, such as Make, Ninja, and Visual Studio.

Using CMake with IDEs

Visual Studio

Visual Studio has excellent CMake integration starting from version 2017. To use CMake as the build system for your project:

  1. Open Visual Studio and choose “Open a project or solution.”
  2. Navigate to the root directory of your CMake project and open the CMakeLists.txt file.
  3. Visual Studio will generate the project files based on the CMake configuration. You can build, debug, and run your project from within the IDE.

CLion

CLion, a popular C++ IDE developed by JetBrains, fully supports CMake as the build system. To use CMake in CLion:

  1. Create a new project in CLion and choose “Import Project from Sources.”
  2. Navigate to the root directory of your CMake project and select the CMakeLists.txt file.
  3. CLion will automatically configure the project using CMake and enable build and run functionalities.

2. Bazel

Bazel is an open-source build system developed by Google. It focuses on providing fast and correct builds in large-scale projects. Bazel uses a high-level build language called Starlark.

Using Bazel with IDEs

Visual Studio Code

Visual Studio Code (VS Code) offers extensions for integrating Bazel into your C++ projects. Install the “Bazel” extension by Bazelbuild to benefit from features like IntelliSense, build target management, and test execution.

  1. Open VS Code and install the “Bazel” extension from the Visual Studio Code Marketplace.
  2. Open the root directory of your Bazel project in VS Code.
  3. VS Code will automatically detect the Bazel project configuration and provide build tools and features.

CLion

CLion provides experimental support for Bazel as a build system through its Bazel plugin. To enable Bazel support in CLion:

  1. Install the Bazel plugin from the JetBrains Plugin Marketplace.
  2. Open your Bazel project in CLion and configure the Bazel target.
  3. You can then build, run, and debug your Bazel project from within CLion.

Conclusion

Incorporating a robust build system into your C++ development environment is essential for efficient and reliable project workflows. IDEs like Visual Studio and CLion offer seamless integration with popular build systems like CMake and Bazel, making it easy to configure, build, test, and debug your projects.

By leveraging the power of these build systems and IDEs, you can focus more on writing code and less on managing complex build configurations. Happy coding!
