This is interesting. It will certainly give a boost to Meson, which is in part a better CMake (the compilation model is very similar). It probably makes a lot of sense for SciPy given the alternatives, but from an ecosystem perspective it

It can be worse than that when those sites get a full multi-line result billing whereas the original stackoverflow answer gets a single-line subheading under some other SO result.

> You should always be able to update CMake and have it continue to work. CMake hard-codes the absolute path to itself all over the place. Any time a package manager that relies on symlinks (eg homebrew) updates the CMake package, every

Julia did that for binary dependencies for a few years, with adapters for several linux distros, homebrew, and for cross-compiled RPMs for Windows. It worked, to a degree -- less well on Windows -- but the combinatorial complexity led to ma

CFFI [1] is a step in the right direction, inspired by LuaJIT's CFFI. It originated from the PyPy folks and is supported in PyPy [2]; it's also supported to some degree by Numba [3]. I don't know what level of C call optimiza

I won’t comment on the relative numbers because there are top-notch developers in many language communities. I think the more important point is that Julia has attracted enough first-rate people to self-sustainably build out an ecosystem

It’s been a couple years since I looked, but I recall LLVM’s CMake being among the cleanest I’ve ever seen.

In the context of pandas, 3 GB of (raw, uncompressed) data could easily require 30 GB of RAM, and that kind of overhead adds up quickly.

A small warning for code with many CMake ExternalProject dependencies: the defaults for cmake+ninja will recursively run `ninja -jN` for each level of the dependency tree, which can spawn a very large number of compile jobs. There is a prop

There seems to be a problem running the example under python 3.6 used in the docker container. Investigating. Please ping us (tiledb.com for contacts) and I will let you know when the docker image is updated.
