   1 # - Find CABLE
   2 # This module finds if CABLE is installed and determines where the
   3 # include files and libraries are.  This code sets the following variables:
   4 #
   5 #  CABLE             the path to the cable executable
   6 #  CABLE_TCL_LIBRARY the path to the Tcl wrapper library
   7 #  CABLE_INCLUDE_DIR the path to the include directory
   8 #
   9 # To build Tcl wrappers, you should add shared library and link it to
  10 # ${CABLE_TCL_LIBRARY}.  You should also add ${CABLE_INCLUDE_DIR} as
  11 # an include directory.
