CMake/Modules/FindTCL.cmake

#
# 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_LIBRARY      = the full path to the tcl library found (tcl tcl80 etc)
#  TCL_INCLUDE_PATH = the path to where tcl.h can be found
#  TK_LIBRARY       = the full path to the tk library found (tk tk80 etc)
#  TK_INCLUDE_PATH  = the path to where tk.h can be found
#
