I'm not sure I've even seen a recent, large C++ project that didn't depend on Python or some other external scripting language just to build it, so it's kind of hard to imagine using C++ itself to solve the problem that using C++ creates.

I worked with a guy in a C++ RPC team (think Envoy, but proprietary). He wrote the build tool that was used by our team, which maintained several fairly large C++ programs and libraries. He wrote it all in C++. He was of the opinion that most scripting tasks on the team could be accomplished with a small C++ program. It helped that we had a portable kitchen sink of libraries at our disposal, but he wasn't above using std::system to avoid the hassle.
