Review: Why do we use Make and CMake tools? The main reasons are to automate the build process, manage dependencies, and simplify cross-platform development for complex project compilation requirements: Large C++ projects often consist of multiple source files, header files, and library dependencies, making manual compilation commands (like <span>g++</span>) error-prone and inefficient. Dependency Management: Build … Read more

For larger projects, manually writing Makefile files can be very challenging. Firstly, the structure of Makefile files is complex, and secondly, they are often constrained by the development environment. If the environment parameters differ or paths change, modifications to the Makefile may be necessary to adapt to these changes. Autotools is a suite of tools … Read more
