#
# 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.
#
# Use some tricks to find the cable executable relative to somewhere
# in the system search path. CMake will collapse the relative paths
# automatically.
FIND_PROGRAM(CABLE
NAMES cable
../share/Cable/bin/cable
../Cable/bin/cable
PATHS /usr/share/Cable/bin
/usr/local/share/Cable/bin
"C:/Program Files/Cable/bin"
)
# Get the path where the executable sits, but without the executable
# name on it.
GET_FILENAME_COMPONENT(CABLE_ROOT_BIN ${CABLE} PATH)
# Find the cable include directory in a path relative to the cable
# executable.
FIND_PATH(CABLE_INCLUDE_DIR WrapTclFacility/wrapCalls.h
${CABLE_ROOT_BIN}/../include)
# Find the WrapTclFacility library in a path relative to the cable
# executable.
