| # - 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 |
| # |
