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.
