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.

Automate Build Commands with Custom Scripts:
Pair CMake with Ninja for Faster Builds:

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.
