Make Build Tool

Make is a classic and powerful build automation tool that automatically builds executable programs and libraries from source code. It operates by reading a special file, typically named `Makefile`, which defines a set of rules specifying how to generate target files from a set of source files and their dependencies. Make's primary advantage is its efficiency; by checking the modification times of files, it intelligently determines which parts of a project need to be recompiled, avoiding unnecessary work and significantly speeding up the development cycle. Although foundational in the Unix/Linux world and traditionally associated with C/C++ projects, its core concepts of dependency management and incremental builds have influenced the design of countless modern build systems.
