#
# This module finds if CABLE is installed and determines where the
# include files and libraries are. This code sets the following variables:
#
# CABLE = the full path to the cable executable
# CABLE_TCL_LIBRARY = the full path to the Tcl wrapper facility library
# CABLE_INCLUDE_DIR = the full path to the cable 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.
