Hi guys,

I wonder why automake has become the build system for Bitcoin Core?
I mean - why not cmake which is considered better?
Can you please point to the relevant discussion or explanation?

Thanks,

Considered by whom? Automake is the standard and I prefer it as it
requires
no additional install on most systems. For that, I consider it better.
Well, here are some quotes about CMake build tools...

JetBrains (2014)
================
Our brief research showed that CMake and ‘make’ were the most popular
cross-platform tools, having ~30% of users each, while both Autotools
and qmake had less than 7% of users. So we ended up with CMake and make.
[https://blog.jetbrains.com/clion/2014/09/cmake-vs-the-others-round-1/]

KDE Project (2006)
==================
Now the next big change is happening: KDE is leaving the aging "autotool"
build chain behind. Some developers, not only in KDE, like to nickname
the autotools as "auto-hell" because of its difficult to comprehend
architecture. So, KDE 4 will feature a completely different build system:
CMake.
[https://lwn.net/Articles/188693/]

Also, there are more advanced build systems:
============================================
- Meson [http://mesonbuild.com]
- Ninja [https://ninja-build.org/]

All of them (CMake, Meson, Ninja) had a goal to replace automake.
Was there any discussion about choosing the best build system for
Bitcoin Core?

Thanks,

What exact problem are you trying to fix for bitcoin-core?

Each build system have their pros and cons, and what you need it the
right tool for the job. Unless there is a specific problem to solve and
that cmake can solve it without causing other issues, why would you want
to change?

Or better yet, convert yourself bitcoin-core to cmake and show the
developers that it makes build config simpler without scarifying
features (cross-platform builds, gitian...) then maybe they'll adopt it.
