How do you download CCXT header file?

I’m working on a CCXT C++ code with the help of Chatgpt.
All I need is the ccxt header file, but I failed to find it after downloading the ccxt library from this website: GitHub - ccxt/ccxt: A JavaScript / Python / PHP cryptocurrency trading API with support for more than 100 bitcoin/altcoin exchanges

Is CCXT not currently supported in C++?
And if I were to use C++/C for faster execution, would I have to use another library?

CCXT is a community-driven library, please feel free to open issue in the github repository.
