C++ Compiler Optimization with CMake

How your C++ code is compiled directly impacts its execution speed and binary size. Understanding how to control these compiler optimizations through your build system is essential for writing high-performance software. This text-based course guides you through configuring compiler optimization levels using CMake, the industry-standard build system. You will transition from default, unoptimized builds to fine-tuning your compiler flags for development, debugging, and production environments. What you'll learn: Understand foundational compiler optimization concepts and terminology; Configure standard CMake build types such as Debug, Release, and MinSizeRel; Apply compiler-specific optimization flags safely using target compile options; Implement generator expressions to write portable, compiler-agnostic build scripts; Analyze how optimization levels impact compilation time and binary performance. You will start by learning core compilation and optimization concepts before moving on to practical configuration. Through clear written explanations and structured code snippets, you will learn how to write clean, modern, and cross-platform CMake scripts. This course is designed for beginner C++ developers and software engineers looking to gain control over their build process, with no prior experience in advanced CMake configuration required.
