Subject: Surveying interest regarding CMake
From: friendlyanon_@hotmail.com (=?UTF-8?B?SG9ydsOhdGggVi4=?=)

Hello internals,

I'm writing to you to find out what the reception here is regarding the
idea of moving the PHP project to build using CMake.

I have looked around and I found 2 attempts of doing just that in the
past (in 2008 via GSoC and something else maybe in 2014 that I couldn't
find the exact info for before writing this email), but nothing came of
those attempts. I have also briefly suggested the idea to Sara Golemon
on Reddit and she didn't seem to be completely against the idea.

For my attempt, I would also optionally use Conan as a means of fetching
dependencies in a cross-platform manner, which would make the need for
OS specific SDKs (like the Windows one) unnecessary. Thanks to CMake's
amazing customizability, using Conan can be made completely optional and
PHP could still continue to build with just system dependencies.

Moving the build system to use CMake instead of the current split
between a *nix and Windows solution would bring everything to one place
and providing CMake bits in the install interface of PHP would make it
easier to develop and use PHP from a development point of view thanks to
CMake packages.

I am planning to make a YouTube video of the whole process of me doing
this grunt work, while I explore the current situation regarding
building PHP and explain what I do and why. I think that it'd generally
be a good thing to have such a video for transparency and it could be
interesting educational material for people who are in a similar
situation and wish to move to building their projects using CMake.

For reference, I occasionally contribute to the CMake project, I'm the 
author of https://github.com/friendlyanon/cmake-init which aims to 
simplify quickly scaffolding a CMake project that's setup correctly and 
I'm in the process of peer reviewing a CMake related book.

Let me know what you think.

Regards,
Horváth V.
