[Python] Cannot import .pyb / .dll file into Python after compiling C++ code with pybind11 on...

My OS is Windows 10, I use G++ compiler, VS Code. I attempt to compile an example pybind11 file into a Python object. The C++ code looks as follows:

#include <pybind11/pybind11.h>

int add(int i, int j) {
return i + j;
}

namespace py = pybind11;

PYBIND11_MODULE(cmake_module, m) {
m.def("add", &add, R"pbdoc(
Add two numbers

Some other explanation about the add function.
)pbdoc");
};


To compile the project I use the CMake script:

cmake_minimum_required(VERSION 3.30.2)
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_FLAGS "-Wall -Wextra -pedantic -shared")
set(CMAKE_CXX_FLAGS_DEBUG "-Werror -Og")

# Specify the path to pybind11 if it's not installed globally
set(PYBIND11_DIR "C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python312\\Lib\\site-packages\\pybind11")

# Specify the path to the Python interpreter
set(PYBIND11_FINDPYTHON "C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python312\\python.exe")

# Find pybind11
find_package(pybind11 REQUIRED PATHS ${PYBIND11_DIR})

# Find Python components
find_package(Python COMPONENTS Interpreter Development REQUIRED)

# Include directories for Python headers
include_directories(${Python_INCLUDE_DIRS})

# Create the module
set(MODULE_NAME cmake_example)
pybind11_add_module(${MODULE_NAME} src/test.cpp)



After successfully building the file, I get a cmake_example.cp312-win_amd64.pyd file in a build folder. Here, I run import cmake_example, which lead to the following error: ImportError: DLL load failed while importing cmake_example: The specified module could not be found.

I use Python 3.12.4, if it's somehow relevant.

My attempts to solve the issue:

• Provided a path to my Python interpreter in CMake
• Tried os.add_dll_directory("path/to/build/dir")
• Moved the compiled .pyd file to the "C: Users\User\AppData\Local\Programs\Python\Python312\DLLs" directory.
