# - Find Tcl includes and libraries.
|
|
# 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:
|
|
# - The stub libraries are now found in FindTclStub.cmake
|
|
# => they were only useful for people writing Tcl/Tk extensions.
|
|
# - TCL_LIBRARY_DEBUG and TK_LIBRARY_DEBUG were removed.
|
|
# => 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.
|
|
# - TK_INTERNAL_PATH was removed.
|
|
# => 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.
