#.rst:
# FindTCL
# -------
#
# TK_INTERNAL_PATH was removed.
#
# This module finds if Tcl is installed and determines where the include
# files and libraries are.  It also determines what the name of the
# library is.  This code sets the following variables:
#
# ::
#
#   TCL_FOUND              = Tcl was found
#   TK_FOUND               = Tk was found
#   TCLTK_FOUND            = Tcl and Tk were found
#   TCL_LIBRARY            = path to Tcl library (tcl tcl80)
#   TCL_INCLUDE_PATH       = path to where tcl.h can be found
#   TCL_TCLSH              = path to tclsh binary (tcl tcl80)
#   TK_LIBRARY             = path to Tk library (tk tk80 etc)
#   TK_INCLUDE_PATH        = path to where tk.h can be found
#   TK_WISH                = full path to the wish executable
#
#
#
# In an effort to remove some clutter and clear up some issues for
# people who are not necessarily Tcl/Tk gurus/developpers, some
# variables were moved or removed.  Changes compared to CMake 2.4 are:
#
# ::
#
#    => they were only useful for people writing Tcl/Tk extensions.
#    => these libs are not packaged by default with Tcl/Tk distributions.
#       Even when Tcl/Tk is built from source, several flavors of debug libs
#       are created and there is no real reason to pick a single one
#       specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
#       Let's leave that choice to the user by allowing him to assign
#       TCL_LIBRARY to any Tcl library, debug or not.
#    => this ended up being only a Win32 variable, and there is a lot of
#       confusion regarding the location of this file in an installed Tcl/Tk
#       tree anyway (see 8.5 for example). If you need the internal path at
#       this point it is safer you ask directly where the *source* tree is
#       and dig from there.
