Update on the new C++ plugins

Gradle's new C++ plugins have received several major updates since their initial introduction. Key new features include starter templates for C++ projects via the Build Init Plugin, target machine modeling allowing configuration of OS and architecture variants (x86, x86-64), and source dependencies enabling Gradle to consume other projects directly from source—including those built with CMake. New documentation chapters for building and testing C++ projects were released in Gradle 5.5, along with reference chapters for native and IDE plugins. IDE support now covers Visual Studio, CLion (via JetBrains' Gradle tooling API integration), and Xcode. The plugins are still a work in progress with some limitations, such as limited configurability of model elements like debuggability.
