# 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.
