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