We will keep account.cpp unchanged with respect to the previous two recipes and only modify account.hpp:
#pragma once#include <pybind11/pybind11.h>class Account {public: Account(); ~Account(); void deposit(const double amount); void withdraw(const double amount); double get_balance() const;private: double balance;};namespace py = pybind11;PYBIND11_MODULE(account, m) { py::class_<Account>(m, "Account") .def(py::init()) .def("deposit", &Account::deposit) .def("withdraw", &Account::withdraw) .def("get_balance", &Account::get_balance);}
We will follow the pybind11 documentation "Building with CMake" (https://pybind11.readthedocs.io/en/stable/compiling.html#building-with-cmake) and introduce the pybind11 CMake code using add_subdirectory ...
