CMake remains one of the most popular build systems in 2025 for managing project configurations across different platforms. One critical task during the build process is managing and listing all dependencies of a project. Understanding your project’s dependencies helps ensure a smooth build process and avoids runtime errors.
Understanding Dependencies in CMake
Dependencies in CMake define the relationship between different components of your project. Managing these dependencies efficiently is key to harnessing the full power of cross-platform builds. If you’re new to this subject, start by exploring cmake dependencies.
Why List Dependencies?
Listing all dependencies gives you a comprehensive overview of what your project needs to function correctly. It helps identify potential issues early on, as well as simplify debugging by ensuring that all necessary components are correctly integrated.
Steps to List All Dependencies in a CMake Build
1. Use cmake --graphviz Command
CMake offers a handy feature to visualize dependencies using Graphviz. The command below generates a .dot file, which can be further transformed into a visual graph.

cmake --graphviz=output.dot path/to/source

This command creates a graph of target dependencies which you can visualize using Graphviz tools.
2. Leverage CMake’s Built-In Commands
CMake’s built-in command target_link_libraries() is critical for managing dependencies between targets. To list dependencies, you can inspect the CMakeLists.txt file for this command and others defining dependency relationships.
3. Explore cmake --build --trace
For a deeper dive into the build process, cmake --build --trace provides a trace of all commands executed during the build, enabling you to spot dependencies as they’re linked.
4. Use External Tools
External tools like CMakeGUI offer user-friendly interfaces to explore dependencies. The GUI allows you to quickly navigate through projects and their dependencies, offering a high-level overview that can be indispensable.
5. Integrate with CI/CD
Integrating dependency checks into your Continuous Integration/Continuous Deployment (CI/CD) pipelines ensures that dependencies are systematically verified, reducing the risk of failures.
