# 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
