is a cross-platform, open-source build tool with built in support for SWIG. It can detect the SWIG executable,
many of the target language interpreters and libraries for linking against.
It can then use this information to generate a makefile/project file for a host of different compilers/IDEs.

There is growing support for SWIG in some build tools, for example <a href="http://www.cmake.org">CMake</a>
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).
