CMake Tutorial: Selecting a Generator from `CMakeLists.txt`

CMake is a powerful cross-platform build system generator. It doesn't build your project directly; rather, it generates build scripts (like Makefiles, Visual Studio solutions, or Xcode projects) tailored to your chosen build environment. A generator is the component of CMake responsible for creating these build scripts.

While CMake typically infers the best generator based on your system and available tools, sometimes you need to explicitly specify which generator to use. This is particularly useful when:

*You have multiple IDEs or build tools installed:* You might want to target a specific version of Visual Studio, or prefer using Ninja over Makefiles.
*You need cross-compilation or remote development:* You might be generating build files for a different architecture or a remote machine.
*You want to enforce consistency across different platforms:* Explicitly setting the generator ensures everyone on the team uses the same build environment.
*You're using a CI/CD pipeline:* Automated build systems often require explicitly specifying the generator for repeatable builds.

This tutorial will guide you through the process of selecting a CMake generator directly within your `CMakeLists.txt` file. While command-line generator selection (`-G`) is more common, there are scenarios where in-file selection is preferable, especially for projects with specific generator requirements that should be part of the project definition.

*Why In-File Generator Selection?*

Selecting a generator in `CMakeLists.txt` is generally discouraged unless absolutely necessary. The preferred approach is to use the `-G` option on the command line. Here's why:

*Flexibility:* Command-line selection gives users the freedom to choose their preferred build environment without modifying the project source.
*Portability:* A `CMakeLists.txt` file that doesn't hardcode a generator is more portabl ...
