Are you insulting this mailing list?
How do you think we made it so far without cmake? Honestly?
The very fact you're discussing qmake and qbs just show that you know
about them, and that you know what they provide cmake cannot provide

Woah, you're ass is so shinny i can't see the light.

Yes, come on, why do i have to define a custom "toolchain file" each
time someone fart?
Can't you just understand the good old gnu configure triplet? Or the
concept of sytem/user wide profile? (qbs profile, qmake specs)
Why does every single project has to provide it's own set of CMake
Have you ever thought about the problem?
Well, i doubt that. "If it works on my Windows machine, then it works
everywhere", right? (provocative sarcasm really)

This is awesome.
They can use gcc to build a QNX app... Thanks CMake to allow QNX to
exists... This real-time kernel could never have existed without the
help of CMake.
My first experience with QNX, was.. at least 20 years ago. I'm not
even sure CMake existed back at that time.
But hey, you're revolutionizing the world, i cannot fight obviously...

Lol, did you run out of google searches? Honestly i can throw random
links too. Did you click "I'm felling lucky" or what?

Yeah right, problem solved then! Ship it! Come on, let's do it!
Let's make an announcement:
CMAKE FULLY SUPPORT IOS.
PS: well, not exactly, please carrefully read the small prints.
> Also, just because CMake now has acquired *official* support for iOS does not mean that it hasn't been working for a long time. There were people shipping iOS apps with CMake five years ago - and this is due in part to CMake having a *large* community, unlike qmake / qbs, which means that even if CMake does not directly support $FEATURE, chances are that you can find an aptly-licensed open-source library that you can use to augment your build with and achieve what you want.

Man, your google skills outpace me to such an extent that i cannot be
bothered wasted more time...
