Build prerequisites are missing some components about oni2 HOT 3 CLOSED

@Samonitari on Windows you need windows-build-tools for compiling native binaries with node-gyp. It's mentioned here https://github.com/nodejs/node-gyp#on-windows

As pointed out in #56 , debian users should change their /etc/apt/sources.list to get libharfbuzz-dev from sid repo.
Apart from that, I had no issues installing oni2 on debian.

Sorry for the late answer!

First, I failed to mention in this ticket that I tried building oni2 on Windows (first)
Anyways, it can be easy to be lost in the transitive dependency chain, which is not explicit as it is.
My build steps were:

0. I had native (C++) development environment and python3 already
1. Look at the prerequisities: git was already installed, I needed esy
2. Go to esy Get Started: realized I need npm/node,js
3. Go to Node.js: downloaded and installed the LTS relase
4. Go back to 2: installed esy with npm.
5. Do the build steps (couple times before textmate got included)
6. Do the textmate build: error msg says node-gyp fails on print command
   -> quickly realize the installed python3 is called but it expects python2
7. Install python2, add it to the front of the PATH in the build cmd shell (as I don't want to break my python3 environment) -> happyness!

Nowhere in that chain I have been notified that I need Python 2 (which is frankly a bit lame, considering it'll soon be marked EOL, but that's another story, and its node-gyp's fault).
I'll admit I'm not versed in web-related programming language stacks, but I didn't even realized node-gyp has been installed somewhere (was it installed with node.js or did esy install it?), so how should I be aware of its missing dependencies?

I hope you don't get it as nitpicking (I am constantly checking out the changes of the repo, and I am thrilled by every minor progress), and maybe every tester already has node-gyp, but maybe I am not the only one to have to figure it out. A little note should not be distrubing in the prerequisites.
