Embracing Modern CMake
summary
Argues that “Modern CMake” is a target‑centric style introduced around 2011 and present since CMake 3.1 (Dec 2014), urging migration from directory variables and include_directories to target_include_directories and target_compile_definitions, using target_link_libraries with double‑colon names (e.g. Qt5::Widgets) and imported/alias targets so CMake enforces build order and usage requirements. Covers PUBLIC/PRIVATE/INTERFACE semantics, generator expressions for config‑time conditions, policies via cmake_minimum_required, and notes recent additions like target precompiled headers.
