CMake has become a vital tool in modern software development, serving as a powerful cross-platform build system. A fundamental concept within CMake is the “target.” Targets in CMake can be executables, libraries, or custom build steps defined within a project. They encapsulate source files, build instructions, and dependencies, streamlining the build process.

In 2025, creating a CMake target remains a straightforward yet essential task for developers looking to build robust software projects. Let’s explore how to create a CMake target and manage it effectively.

How to Create a CMake Target

To create a target in CMake, you will primarily use commands like add_executable() or add_library(), depending on whether you’re defining an application or a library.

Step-by-Step Guide to Creating a CMake Target

1. Install and Set Up CMake: First, ensure you have CMake installed on your system. This can usually be done through your package manager.

2. Create a CMakeLists.txt File: This file will contain all the instructions for CMake to process your build.

3. Define Your Target: Use add_executable() for executables or add_library() for libraries. For example:

1
2
3
4
5

   cmake_minimum_required(VERSION 3.21)
   project(MyProject)

   # Create an executable target
   add_executable(MyExecutable main.cpp)

1. Specify Include Directories and Libraries: Add any necessary include paths and linked libraries using target_include_directories() and target_link_libraries().

2. Generate Build Files: Run CMake to generate the build files (e.g., Makefiles or Ninja files) based on your CMakeLists.txt.

3. Build the Target: Use your build system (e.g., make or ninja) to compile your target.

Manage CMake Targets

Managing CMake targets efficiently involves understanding their properties and the surrounding ecosystem. These resources can guide you on specific use cases:

• Replicate a CMake Target: Learn how to replicate targets efficiently across projects.
• Duplicate CMake Target Tutorial: A detailed tutorial for duplicating CMake targets.
• CMake Target Properties: Explore how to review and understand target properties in CMake.
• CMake Target Removal: Strategies for removing or disabling targets in CMake.
• CMake Target Architecture Detection: Guidance on detecting the target architecture using CMake.

CMake targets are the cornerstone of structured, modular project management in software development. By understanding how to create and manage these targets, developers can enhance their build processes significantly in 2025 and beyond.
