2․1 Target-Based Programming in CMake

Target-based programming in CMake simplifies dependency management by defining build rules with add_executable and add_library․ It enhances clarity and reduces errors by leveraging properties and interfaces, promoting modular and maintainable C++ projects․ This approach aligns with modern practices, ensuring efficient builds and proper propagation of settings across project hierarchies․ It is a cornerstone of effective CMake usage․

2․2 Property-Based Configuration

Property-based configuration in CMake allows for flexible and maintainable build setups․ By defining properties at the target, source, or directory level, developers can control compile flags, include directories, and library dependencies․ This approach reduces reliance on custom scripts and variables, enabling clearer and more reusable build configurations․ It streamlines dependency management and ensures consistency across project modules․

2․3 Effective Use of CMake Policies

CMake policies ensure backward compatibility and control behavior changes․ By setting policies via `cmake_policy`, developers can manage deprecated features and adapt to new CMake versions․ This approach prevents unexpected build issues and aligns projects with modern practices․ For example, `cmake_policy(SET CMP0021 NEW)` updates include handling․ Always check the cmake-policy(1) manual for detailed guidance on policy usage and compatibility․
