#.rst: # FindSWIG # -------- # # Find SWIG # # This module finds an installed SWIG. It sets the following variables: # # :: # # SWIG_FOUND - set to true if SWIG is found # SWIG_DIR - the directory where swig is installed # SWIG_EXECUTABLE - the path to the swig executable # SWIG_VERSION - the version number of the swig executable # # # # The minimum required version of SWIG can be specified using the # standard syntax, e.g. find_package(SWIG 1.1) # # All information is collected from the SWIG_EXECUTABLE so the version # to be found can be changed from the command line by means of setting # SWIG_EXECUTABLE #============================================================================= # Copyright 2004-2009 Kitware, Inc. # Copyright 2011 Mathieu Malaterre <mathieu.malaterre@gmail.com> # Copyright 2014 Sylvain Joubert <joubert.sy@gmail.com> # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # # * Redistributions of source code must retain the above copyright # notice, this list of conditions and the following disclaimer. # # * Redistributions in binary form must reproduce the above copyright # notice, this list of conditions and the following disclaimer in the # documentation and/or other materials provided with the distribution. # # * Neither the names of Kitware, Inc., the Insight Software Consortium, # nor the names of their contributors may be used to endorse or promote # products derived from this software without specific prior written # permission. # # THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS # "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT # LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR # A PARTICULAR PURPOSE ARE DISCLAIMED.
