MihailRis/voxelcore — reverse-engineered prompt

Build me a C++ voxel game engine called VoxelCore. I want it to open a desktop window, use OpenGL to render a simple voxel world, and feel like the foundation for a block based game rather than a finished game.

Please set it up as a clean CMake project that can build on Linux, macOS, and Windows. Include the basic engine structure, resources, source files, and a small test or demo app that proves the engine runs. It should be easy to compile in release mode, and if possible include Docker support so I can build it without fighting my local setup.

Keep the code organized and readable, with sensible defaults and enough documentation that someone can clone it, install the needed libraries, build it, and run the demo. Look up current docs online if you need to.
