Building Software for the Next Five Years, Not Just the Next Release

As software projects grow, development often becomes slower and less predictable. Builds take longer, and continuous integration results arrive too late to guide developers. Dependencies become hard to reproduce, and gaps in test coverage let regressions reach users. Even well-planned changes become risky because their effects are difficult to evaluate.

These problems are not inevitable consequences of a large codebase. They are often signs that manual processes have not evolved with the project.

One of CMake’s original goals was to replace a manual, platform-specific build process with one that could be automated and reproduced. The same principle applies to the broader software-development workflow: make important processes repeatable, automate them where possible, and provide developers with timely evidence that their changes work.

When builds are reproducible and testing is comprehensive, teams can make substantial changes with greater confidence. Developers spend less time reconstructing environments and diagnosing avoidable failures. That makes it easier for teams to adjust as requirements change.

Build Confidence Into the Development Process

Long-lived software needs reliable processes to manage source code, configure builds, integrate dependencies, test changes, and prepare releases. Consider whether:

• Developers can reproduce builds across supported platforms and configurations.
• Dependencies are declared, versioned, and tested through repeatable processes.
• Continuous integration provides feedback quickly enough to be useful.
• Tests cover new code and protect existing behavior.
• Build times, test performance, and intermittent failures are tracked over time.
• New contributors can work effectively without relying on undocumented knowledge.

The goal is not to support every platform or anticipate every future technology. It is to automate the workflows your project depends on and make their results visible, consistent, and actionable.

Practices That Support Long-Lived Software

For more than two decades, Kitware has developed and maintained open source technologies including CMake, VTK, ParaView, and CDash. These projects support large communities across diverse platforms and demanding computing environments. The practices behind them can also strengthen proprietary products and internal development programs.

Automate reproducible builds

A reliable build process should describe how software is configured and compiled across its supported environments. CMake provides a portable foundation for automating those steps without maintaining a separate build system for every platform.

Integrate dependency management

Documenting dependencies is not enough. Dependencies should be declared, versioned, resolved, and tested through repeatable workflows. CMake and package managers such as Spack can help teams manage these relationships and reproduce development environments.

Make testing part of every change

Continuous integration should exercise supported configurations and return actionable results promptly. Tests should grow alongside the code, while coverage analysis identifies important paths that remain untested. Together, these practices reduce regressions and give developers greater confidence when improving or restructuring the software.

Monitor development performance

Slow builds and delayed test results interrupt development and discourage frequent validation. CDash brings build, test, and coverage results together across platforms. It also helps teams track execution times and intermittent failures, making it easier to identify bottlenecks and declining reliability.

Establish clear contribution workflows

Version-control conventions, code review, automated checks, release processes, and clear ownership all affect how efficiently a team works. These practices should be easy for new contributors to follow and flexible enough to evolve with the project.

Apply Proven Practices to Your Project

Kitware’s open source projects have survived decades of changes in platforms, hardware, and development practices. Kitware applies that experience to both open source and closed source projects, helping teams improve:

• Version-control and collaboration practices
• Cross-platform builds
• Dependency management
• Continuous integration and automated testing
• Coverage and performance monitoring
• Release engineering
• Agile development processes

The result is not merely better infrastructure. It is a development process that lets teams move faster, make larger changes with confidence, and continue improving their software over time.
