Subject: [PATCH] Enforce minimum compiler versions and C++20 support

Added checks to validate minimum compiler versions and enforce C++20 compatibility for the package. These include GCC 12, Clang 14, Apple Clang 13, MSVC 191, and Visual Studio 17. This ensures compatibility with the required C++ features, preventing builds with unsupported compilers.
