The FindSWIG.cmake shipped with CMake 3.0 does not yet look for the
"cmake3.0" binary, this was added shortly after the 3.0 release.

This file can be removed once the minimum CMake version is 3.1 or greater.

+# 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
