# 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.
