# - 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.
