: Always use a compressed .tar.xz or .7z archive instead of a Git clone to significantly reduce download times. Method 2: Using ExternalProject_Add (Superbuilds)
The ExternalProject_Add module handles downloading and building during the step. This is useful for "superbuilds" where you want to isolate the Boost build environment entirely from your main project.

To download and build the Boost C++ libraries using CMake, you can choose between two main methods: the modern module for seamless integration or the classic ExternalProject_Add for isolated "superbuilds." : Always use a compressed
The FetchContent module downloads Boost during the step, making its targets immediately available to your project. This is the preferred way for simple integration where you want to treat Boost as a subproject. Implementation Example Implementation Example FetchContent with Boost - Code -
