+is a cross-platform, open-source build manager with built in support for SWIG. CMake can detect the SWIG executable
+and many of the target language libraries for linking against.
+CMake knows how to build shared libraries and loadable modules on many different operating systems.
+This allows easy cross platform SWIG development.  It also can generate the custom commands necessary for
+driving SWIG from IDE's and makefiles.  All of this can be done from a single cross platform input file.
+The following example is a CMake input file for creating a python wrapper for the SWIG interface file, example.i:
 </p>
 
+<blockquote><pre>
+
+# This is a CMake example for Python
+
+FIND_PACKAGE(SWIG REQUIRED)
+INCLUDE(${SWIG_USE_FILE})
+
+FIND_PACKAGE(PythonLibs)
+INCLUDE_DIRECTORIES(${PYTHON_INCLUDE_PATH})
+
+INCLUDE_DIRECTORIES(${CMAKE_CURRENT_SOURCE_DIR})
+
+SET(CMAKE_SWIG_FLAGS "")
+
+SET_SOURCE_FILES_PROPERTIES(example.i PROPERTIES CPLUSPLUS ON)
+SET_SOURCE_FILES_PROPERTIES(example.i PROPERTIES SWIG_FLAGS "-includeall")
+SWIG_ADD_MODULE(example python example.i example.cxx)
+SWIG_LINK_LIBRARIES(example ${PYTHON_LIBRARIES})
+
+</pre></blockquote>
+
+The above example will generate native build files such as makefiles, nmake files and Visual Studio projects
+which will invoke SWIG and compile the generated C++ files into _example.so (UNIX) or _example.dll (Windows).
