axomtools/axomic-roblox-dumper ? reverse-engineered prompt

Build me this Roblox dumper tool in C++ so it can be built with CMake and produce two outputs, a shared library for the internal version and a standalone executable for the external version.

I want the project to compile cleanly on a normal setup, with a simple build flow like creating a build folder, running CMake, and making the binaries. The external app should run by itself, and the internal one should be a library that can be injected. Keep the code organized so the common parts are shared between both versions, and make it easy to understand what each part is doing.

If anything about the Roblox offsets or current APIs has changed, look up the current docs or examples online and use whatever is needed to make it work. Please also make the README clearer with the exact build and run steps, and include any small notes needed so someone can use it without guessing.
