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