Hello,
Why again did we choose for autotools as future build system instead of
cmake?
- CMake generates native build scripts for Make (all platforms), XCode,
Visual Studio. Autoconf only does Make.
- CMake has a clearer syntax, m4/autotools is very convoluted
- CMake is very fast
- CMake is supported natively in Qt Creator in the QT SDK, and is used by
many other KDE/QT as well as other open source applications. Many people
discourage the use of autotools for new projects.
A CMake build system for bitcoin is already integrated into rpcminer,
available here:

I dont think anyone really made a conscious decision one way or the
other, someone submitted an autotools patch and thus people started
talking about when we were going to merge autotools. That said, the
autotools stuff needs redone before it would be merged anyway. So it
would be up to whoever writes the build system. However, autotools is
more standard than CMake, and since its a shell script, you dont have to
install CMake which doesnt come standard on almost any distros (AFAIK).

CMake is also very standard, used by many projects, and is available in many
distros.
For debians it's as simple as apt-get install cmake, which is not a big
problem as you need to install the other dependencies (such as boost) as
well to build.
Fedora/redhat also seems to have the package 'cmake'. I don't think there is
any modern distro that doesn't have it as a package.

I don't really care much either way, but cmake doesn't follow the standard
build procedure (./configure && make && make install), though I imagine
./configure could be emulated with some script.

It would change the sequence to
cmake . && make && make install
So a shell script named 'configure' that starts 'cmake .' is the most easy
case :-) Probably it'd also need to pass through some command line args, for
example --prefix.

And --datadir --mandir --randomobscurecrap CXXFLAGS=-O9, etc
Don't forget --help listing all the useful options... that's the big thing I
miss with CMake-stuff.

Cmake is just as bad as autotools, just with a different syntax and more "buzz" behind it right this second. I don't see any advantage to it over autotools unless you're not familiar with either and even then I wouldn't really call it an advantage. It's just different.
It also requires a dependency that isn't installed by default anywhere, as already mentioned, and is less known outside of some obscure qt/kde circles and so finding people who are familiar with it and are willing to maintain it is more difficult.
Autotools is the devil you know.
You'll probably throw out that mysql and compiz have switched to it, but really, those projects aren't something that should be emulated by anyone. Ever.

So, what about native build script generation for other platforms? autotools
can only generate makefiles (with at least two intermediate code generation
steps), which is quite limited.
IMO cmake is simple and elegant compared to the autotools monster. I don't
see why it would be "just as bad". And I have quite some experience with
both systems. Autotools is a hell to debug. cmake certainly isn't perfect,
but at least it's a leap forward.

Yes, apart from that only obscure projects such as LLVM, Blender, and
OpenCV are using it. Nothing of any importance.
BTW for cmake there is "ccmake" which is even better than configure --help
as it offers an interactive interface for configuration.

This would be true if gmake didn't build/run basically everywhere; but, it does.

Don't get me wrong, I'm not defending autotools' design or implementation. It is; however, more ubiquitous and understood by a much wider audience.

I would say that's actually a mark against cmake. If you need a gui to select build options because your cli doesn't have proper help output something is wrong.
If you're willing to setup and maintain a cmake build environment I wouldn't say it should be rejected outright. Speculating about it without an implementation to compare seems like a waste of time.
Especially when jaromil already has a mostly-functional autotools setup. It needs tweaking still and some changes to catch up and rebase, but it works. He also already did the tedious work to rearrange the source tree to make adding any auto-configuration tool for the build environment easy to drop in place. (Which is already merged.)

It doesn't for the native build systems on at least Windows and OSX. Yes,
you can get gmake to run, but it's a hack.

You don't need to use the UI. It's just a convenience. Command line can
simply be used if you want.

As I said in my opening post, there *is* a cmake build system implemented

puddinpop's stuff is all ancient/obsolete. If you want people to consider it,
you should probably make a new branch.

I have no preference for any particular project build system. If a system
* is easy enough to set up (included in standard repositories, eg.)
* allows building of the bitcoin codebase on several linux distro's
* does cross-compilation to windows
* supports osx
* is easy to maintain
* it is not too hard to adapt other GUI's to use it (bitcoin-qt,
maybe others as well, i hear about a cocoabitcoin?)
* gets implemented and tested to support all of the above
.. i have no problem with choosing that system for future versions.

autotools is indeed "the devil we know" which works automatically on
all supported platforms save VC++ It is also the easiest to package,
as all distros already have macros and scripts specifically designed
to integrate autotools packages into their package build systems.
cmake simply does not have that level of uptake.

I'm willing to do it, but the priority is not that high.
I'm currently sticking with qmake, as apart from boost library name
auto-detection, I had no problems with it and it works well enough for a
relatively small project such as bitcoin.
