+# Find CABLE
+#
+# This module finds if CABLE is installed and determines where the
+# include files and libraries are. This code sets the following
+# variables:
+#
+# ::
+#
+# CABLE the path to the cable executable
+# CABLE_TCL_LIBRARY the path to the Tcl wrapper library
+# CABLE_INCLUDE_DIR the path to the include directory
+#
+#
+#
+# To build Tcl wrappers, you should add shared library and link it to
+# ${CABLE_TCL_LIBRARY}. You should also add ${CABLE_INCLUDE_DIR} as an
+# include directory.
