That's the reason.
Lex/Bison C generated output used to be very portable
so it was convenient to put them in.

Another reason comes from pregenerated rpc_xxx files
which are used on the win32 port. They were generated
on linux box and them patched a little in order to work
with open source oncprc (see tsp/external/ACPLT-ONCRPC/)
we use on Win32 platform which works perfectly besides the
rpcgen command :((

I admit this is ugly but convenient, waiting for a cleaner
way to go :))

That's seems a good scheme to me and would
ease to support both in-source AND out-of-source build.

This could be used for:
   bison/yacc generated files
   flex/lex  generated files
   rpcgen generated files.

I did begin to write CMake macros to wrap
RPC machinery (see grep for ONCRPC_SETUP)
I'd like doing the same for lex and yacc.

You may either
IF (PRESENT)
  ONCRPC_SETUP
ELSE (PRESENT)
  DO_IT_ANOTHER_WAY
ENDIF()

or update the macro to handle the "pregen case".

I did begin MACRO for lex and yacc I give you the files
if you want to go this way. Others files are already in CVS.
