You mean some people do NOT have GNU Autotools ? :P
Jokes aside, CMake has certainly matured enough for point #2 and is used
by very big projects (KDE for example). Not sure about point #3 though.
I am wondering though, how do you handle Windows with OpenMPI and GNU
Autotools ? I know CMake is famous for being cross-plateform (that's
what the C means) and can generate builds for Windows, Visual Studio and
In any case, I do not see any need to change from one toolchain to
another, although I have seen many projects providing both and that did
not seem to be too much of a hassle. It's still probably more work than
what you want to get into though.
