Sorry for the late answer, I was on vacation. I wrote a SHELL_PATH genex which uses cmOutputConverter->ConvertToOutputFormat(..., SHELL) for the conversion. I decided to name the genex SHELL_PATH instead of TO_SHELL_PATH for the sake of consistency to other genexes like LOWER_CASE. What do you think? If it is okay I would write some documentation as well of course.

Someone will need to think through and propose a specific genex that does the path conversion that makes sense in this context. I think something like $<TO_SHELL_PATH:...> may be appropriate. For referencing command line tools (as argv[0]) the C++ side uses code like this now: this->ConvertToOutputFormat(ccg.GetCommand(i), SHELL) This genex should map to the same conversion internally. -Brad
