   1 # - Find wish installation
   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 #
   6 #  TK_WISH = the path to the wish executable
   7 #
   8 # if UNIX is defined, then it will look for the cygwin version first
