An example pybind11 module built with a CMake-based build system. This is useful for C++ codebases that have an existing CMake project structure. This is being replaced by scikit_build_example, which uses scikit-build-core, which is designed to allow Python packages to be driven from CMake without depending on setuptools. The approach here has some trade-offs not present in a pure setuptools build (see python_example) or scikit-build-core. Python 3.7+ required; see the commit history for older versions of Python.

Problems vs. scikit-build-core based example:

• You have to manually copy fixes/additions when they get added to this example (like when Apple Silicon support was added)
• Modern editable installs are not supported (scikit-build-core doesn't support them either yet, but probably will soon)
• You are depending on setuptools, which can and will change
• You are stuck with an all-or-nothing approach to adding cmake/ninja via wheels (scikit-build-core adds these only as needed, so it can be used on BSD, Cygwin, Pyodide, Android, etc)
• You are stuck with whatever CMake ships with (scikit-build-core backports FindPython for you)

Prerequisites

• A compiler with C++11 support
• Pip 10+ or CMake >= 3.4 (or 3.14+ on Windows, which was the first version to support VS 2019)
• Ninja or Pip 10+

Installation

Just clone this repository and pip install. Note the --recursive option which is needed for the pybind11 submodule:

git clone --recursive https://github.com/pybind/cmake_example.git
pip install ./cmake_example

With the setup.py file included in this example, the pip install command will invoke CMake and build the pybind11 module as specified in CMakeLists.txt.

Building the documentation

Documentation for the example project is generated using Sphinx. Sphinx has the ability to automatically inspect the signatures and documentation strings in the extension module to generate beautiful documentation in a variety formats. The following command generates HTML-based reference documentation; for other formats please refer to the Sphinx manual:

• cd cmake_example/docs
• make html
