How to build a unified C++ cross-platform Windows and Linux (x86_64/aarch64) build system using Python, CMake, and Docker

Developing C++ applications (specifically Qt-based ones) for multiple platforms usually involves a fragmented workflow:

Maintaining separate OS environments (Windows for MSVC, Linux for GCC). Installing and managing massive toolchains (Qt, MinGW, MSVC, aarch64-linux-gnu) on every machine. Managing multiple repository clones or constantly switching IDE contexts. Dealing with CMakePresets.json configuration complexity when supporting multiple compilers and platforms. Lacking a unified interface to switch between native builds, cross-compilation, and containerized builds. Manual environment variable management for toolchain paths, Wine prefixes, and Docker volume mounts. No standardized way to share toolchain configurations across projects or team members.

I want a way to build for Windows (native/MinGW/MSVC) and Linux (x86_64/aarch64) from a single Linux host without manually installing all these toolchains or switching operating systems. Ideally, this solution would:

Support Wine for cross-compiling Windows targets using MinGW or MSVC Use Docker containers for isolated Linux builds (GCC x86_64/aarch64) including Wine for cross-compiling Parse and use CMakePresets.json for preset-based configuration Provide an interactive menu system to select build configurations Automatically configure toolchain environments per platform Allow optional portable toolchain installation to avoid massive system-wide installs

How can one orchestrate a Python-based build script that uses either native compilers or Docker containers to handle these different environments seamlessly?
