Building with CMake
|

===================
|
||||
|
||||
For C++ codebases that already have an existing CMake-based build system, the
|
||||
following snippet should be a good starting point to create bindings across
|
||||
platforms. It assumes that the code is located in a file named
|
||||
:file:`example.cpp`, and that the pybind11 repository is located in a
|
||||
subdirectory named :file:`pybind11`.
|
||||
For C++ codebases that have an existing CMake-based build system, a Python
|
||||
extension module can be created with just a few lines of code:
|
||||
|
||||
.. code-block:: cmake
|
||||
|
||||
cmake_minimum_required(VERSION 2.8)
|
||||
|
