CMake/Modules/FindCABLE.cmake

#
# 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.
