1 niro 433 # - Find SWIG
2     # This module finds an installed SWIG. It sets the following variables:
3     # SWIG_FOUND - set to true if SWIG is found
4     # SWIG_DIR - the directory where swig is installed
5     # SWIG_EXECUTABLE - the path to the swig executable
6     # SWIG_VERSION - the version number of the swig executable
7     #
8     # All informations are collected from the SWIG_EXECUTABLE so the
9     # version to be found can be changed from the command line by
10     # means of setting SWIG_EXECUTABLE
11     #
