Do we still need the configure script or can we switch to cmake as the only build environment?

[farindk]

@fancycode Any opinion on this?

[farindk]

The CI still uses the configure scripts.

TODO:

• use cmake in CI scripts
• add sherlock265 to cmake
• compile Neon code for ARM architectures

Looking at switching to CMake from autoconf I noticed the list of installed tools has a bunch of missing stuff..

This is mostly ok. Most of those were small test programs for development. For some I even forgot what they do.

The only thing that might be some fun to look at is sherlock265. The other ones should either be dropped completely or hidden behind a default-off flag.

Ok, I noticed sherlock265 was mentioned. I figured I'd mention the rest incase they were useful at all. I have no idea what some of those do.
