# - Find tclsh
# 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:
#  TCLSH_FOUND = TRUE if tclsh has been found
#  TCL_TCLSH = the path to the tclsh executable
# In cygwin, look for the cygwin version first.  Don't look for it later to
# avoid finding the cygwin version on a Win32 build.
