3 tips for using CMake with embedded software
CMake is an open-source, cross-platform tool that provides efficient control over the software compilation process through platform-independent configuration files. These files generate native makefiles suitable for any compiler environment, making CMake a versatile and valuable tool for managing complex build environments.
➡️ Use Toolchain Files to Simplify Build Configuration:
* Different build types, such as Debug On-Target, Release On-Target, Simulation, Test, and Code Analysis, require specific configurations.
* Toolchain files help manage these variations, facilitating cross-compilation and implementation swaps.
* Typically, two toolchain files (one for host builds and one for on-target builds) are sufficient.
➡️ Automate Build Commands with Custom Scripts:
* Instead of memorizing long CMake commands, encapsulate them in scripts.
* Custom scripts simplify the build process and reduce errors.
* These scripts can include parameters for toolchain files, build types, and other settings, making them especially useful in CI/CD systems.
➡️ Pair CMake with Ninja for Faster Builds:
* Ninja is a high-speed build system focused on efficiency.
* Using Ninja with CMake can result in compilation times that are 4 to 6 times faster compared to traditional tools like Make.
* Simple setup commands integrate Ninja into the build process, significantly reducing build times and improving development efficiency.
Implementing these tips can streamline the build process for embedded software, making development faster, more efficient, and better suited to modern development practices.
