I’m not sure whether the former is autoconf/make or cmake, but count me as another vote for cmake over meson. CMake has direct support from Microsoft (Visual Studio 2017 can auto-ingest CMake-based files as soon as they’re checked out) and JetBrains CLion and is in use by LLVM, KDE, Qt, Blender, libpng, cURL, LAPACK, MySQL/MariaDB, OpenCV, SDL, the Dolphin Gamecube emulator etc. So the tooling around people using it is there and it’s used by some very large and mature projects covering a variety of domains: I don’t know if it’s “poorly supported” (the documentation leaves something to be desired), but if CMake has trouble down the line a lot of very important projects will be in trouble. It seems like a pretty safe bet given the sheer inertia of the list above. -- Jason Petersen Software Engineer | Citus Data 303.736.9255 ja...@citusdata.com

I’d think you’d need a pretty clear profiling run that points to this as a hot spot before deciding to optimize it. Do you have a query where this is the case? -- Jason Petersen Software Engineer | Citus Data 303.736.9255 ja...@citusdata.com
Re: JIT compiling with LLVM v9.0

I don’t believe there is a similar widely-supported dependency type in yum/rpm, though. rpm 4.12 adds support for Weak Dependencies, which have Recommends/Suggests-style semantics, but AFAIK it’s not going to be on most RPM machines (I haven’t checked most OSes yet, but IIRC it’s mostly a Fedora thing at this point?) Which means in the rpm packages we’ll have to decide whether this is required or must be opt-in by end users (which as discussed would hurt adoption). -- Jason Petersen Software Engineer | Citus Data 303.736.9255 ja...@citusdata.com
