CMake the Most of Software Development - Modern Build Systems Support Scalability

Discover how modernizing your build system with CMake can revolutionize embedded software development, offering unparalleled flexibility and efficiency. Dive into this article to explore the transformative benefits of CMake's cross-platform capabilities and how it integrates seamlessly with contemporary development practices.

Many embedded software developers today cannot take advantage of modern development techniques like DevOps, Test-Driven Development, and simulation because they write software using their microcontroller vendor's IDE. While these integrated environments are convenient for getting a project started quickly, they don't lend themselves well to building multiple configurations; they often build slowly and can create productivity headaches.

Embedded software development doesn't need to be that way. There's a better way that will allow you to leverage modern development techniques and practices while still having the benefits of an integrated IDE: create your own modern CMake build system. I know this sounds time-consuming and difficult, but I will show you how easy it can be.

WHAT'S A BUILD SYSTEM?

A build system is a set of tools and processes used to automate converting source code into executable programs. It includes:

• Cross-compilation

• Configuration management

• Automation

• Integration with development tools

• Resource handling

A typical build system will look like Figure 1.
