# 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
|
|
