An example for using CMake with the SWIG code generator

SWIG Example

This is an example of how to use CMake with the SWIG interface generator. It is meant for those interested to use as a guide to setting up a project built by CMake with interfaces in other languages generated by SWIG.

Languages

This example currently generates interfaces for the following languages:

• Python

I will add languages as I need to use them. Anyone that wishes to add another language, feel free to open a pull request and let me know if there are any issues with using the installation procedure described below with your language.

Installation

A large part of this example is how to install both the C/C++ libraries that SWIG is wrapping as well as the generated wrappers. After a good bit of trying different approaches, the following is the current approach:

---

C/C++ Libraries

C/C++ libraries are installed with the standard make install command with install targets in the CMake configuration.

Wrapper Libraries

Wrapper library installation of both the C libraries and target language libraries generated by SWIG are handled by the target language's packaging system. In addition, a target make install-<LANGUAGE> is added to the CMake configuration to run anything that needs to be run in the target language.

---

It is planned to have make install-<LANGUAGE> install the C/C++ libraries in a language-specific directory, but that functionality has not yet been added.
