Zitat von Philip Lowman <phi...@yhbt.com>:
AFAIK, this is possible with environment variables BISON_M4 or M4, see:
http://osdir.com/ml/parsers.bison.bugs/2007-05/msg00012.html
If that works, maybe the standard bison call should be replaced with a call
to a cmake script that sets this variable correctly.
Excellent find! I don't think add_custom_command supports adding
environment variables though..?

That's why I suggested a cmake script that wraps it. This could
actually be generalized by add_custom_command():
If environment variables are needed, automatically wrap the command
with a cmake script.
Currently, you have to do that manually.
