Modules/FindTCL.cmake

   1 # - Find Tcl includes and libraries.
   2 # This module finds if Tcl is installed and determines where the
   3 # include files and libraries are. It also determines what the name of
   4 # the library is. This code sets the following variables:
   5 #  TCL_FOUND              = Tcl was found
   6 #  TK_FOUND               = Tk was found
   7 #  TCLTK_FOUND            = Tcl and Tk were found
   8 #  TCL_LIBRARY            = path to Tcl library (tcl tcl80)
   9 #  TCL_INCLUDE_PATH       = path to where tcl.h can be found
  10 #  TCL_TCLSH              = path to tclsh binary (tcl tcl80)
  11 #  TK_LIBRARY             = path to Tk library (tk tk80 etc)
  12 #  TK_INCLUDE_PATH        = path to where tk.h can be found
  13 #  TK_WISH                = full path to the wish executable
  14 #
  15 # In an effort to remove some clutter and clear up some issues for people
  16 # who are not necessarily Tcl/Tk gurus/developpers, some variables were
  17 # moved or removed. Changes compared to CMake 2.4 are:
  18 # - The stub libraries are now found in FindTclStub.cmake
  19 #   => they were only useful for people writing Tcl/Tk extensions.
  20 # - TCL_LIBRARY_DEBUG and TK_LIBRARY_DEBUG were removed.
  21 #   => these libs are not packaged by default with Tcl/Tk distributions.
  22 #      Even when Tcl/Tk is built from source, several flavors of debug libs
  23 #      are created and there is no real reason to pick a single one
  24 #      specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
  25 #      Let's leave that choice to the user by allowing him to assign
  26 #      TCL_LIBRARY to any Tcl library, debug or not.
  27 # - TK_INTERNAL_PATH was removed.
  28 #   => this ended up being only a Win32 variable, and there is a lot of
  29 #      confusion regarding the location of this file in an installed Tcl/Tk
  30 #      tree anyway (see 8.5 for example). If you need the internal path at
  31 #      this point it is safer you ask directly where the *source* tree is
  32 #      and dig from there.
