RFC: meson build system (for non-android)

[hanetzer]

I'm willing to do the work if you're up to trying it out. If this is a complete WONTFIX
lemme know.

[anholt]

FWIW, I would love to see this happen.

I would also like to see this, but what has been holding me back is transitioning the Windows support, which I am not set up to test. As a first step, we could make the meson build linux only and retain waf for windows, but this should be a temporary situation. I don't want to end up with two build systems long term.

@null77 Would you be interested in this transition to meson for Windows? Would you have time to ensure we don't break Windows builds or even lend a hand if you have time?

[null77]

Hey, I don't have time to work on this. If you give me some instructions I can verify if they work. Thanks for checking.

[hanetzer]

@null77 I'll have to check with some folks as I've not used meson on windows, but I assume it
can't be terribly hard compared to waf as meson is written in python as well (though its build
scripts are its own mini-dsl), and it uses ninja to build.

@hanetzer Hi! Did you have the chance to make any progress on this? I might have some free cycles, which I could use for this task, but I wouldn't want to duplicate work unnecessarily if you have already started.

[hanetzer]

A bunch of stuff came up in meatspace so I havent' had a chance to look into it yet tbh.
So go ahead :)

[afrantzis]

Hi all! I have a first proposal here: #129 . Currently only for x11/drm/wayland since these are the platforms I am currently set up to use and test.

[afrantzis]

Latest master now has Meson support for X11, Wayland and DRM, and promotes Meson as the preferred way to build when possible. Keeping this issue open for the remaining unported flavors.
