C++ is a big language compared to Python. Many those of us with years of C++ experience don't fully understand the power and complexity of modules, partially because so few libraries and compilers support them as shown by TFA.

I'd recommend becoming an expert in Python modules. How they're packaged, how they're referenced and installed by pip, etc. Then learn how headers and translation units work in C++. How templates operate is an important concept to understand. Jumping right to C++ modules without a deeper understanding of the C++ compiler or without a reference point for other languages' module concepts will only lead to confusion.

If you're totally new to C++, I'd actually recommend reading "The C++ Programming Language" cover to cover just to "know what you don't know" and then roll up your sleeves and get some experience with a hobby project.
