Pedantically: MinGW doesn't "use" a shell. MinGW is a compiler that
could be run under straight Windows command prompt, under MSYS, or
some perverts even run it under the Cygwin bash shell. Also a few
weirdos like myself, who find MSYS's Autoconf support to be
completely broken, use a nonstandard bash shell for MSYS instead of
the default rxvt. http://sourceforge.net/projects/mingw-install
really saved my bacon on some legacy Autoconf build issues I was having.
So, I think shell identification is quite valuable.
OK, you seemed to miss my point. When you run cmake, you can detect
the shell used at cmake time. However,
there is no promise that that same shell will be used at make time.
That is the reason I had to create so many different named generators,
so that the user can tell me which shell they are going to use.
Hrm. I wonder if names like GENERATOR_MSYS, GENERATOR_MSVC71, etc.
would make this relationship clearer to people. It isn't burning a hole
in my pocket, but something to consider about canonization.
But if you need that information you can look at the generator used.
I guess it's getting easier to find these variables, now that the CMake
2.5 documentation has wiki URLs, but it would still be good to have them
in the installed documentation. I'm pinging bug / feature request #3752.
Cheers,
