PowerVR-sdk
PowerVRのグラフィックエミュレーターのライブラリーです。多分、MacOS上で唯一のOpenGLに対するEGLの実装だと思われます。
$ brew list powervr-sdk /usr/local/Cellar/powervr-sdk/4.3/include/EGL/ (3 files) /usr/local/Cellar/powervr-sdk/4.3/include/GLES/ (4 files) /usr/local/Cellar/powervr-sdk/4.3/include/GLES2/ (3 files) /usr/local/Cellar/powervr-sdk/4.3/include/GLES3/ (4 files) /usr/local/Cellar/powervr-sdk/4.3/include/KHR/khrplatform.h /usr/local/Cellar/powervr-sdk/4.3/include/vulkan/ (2 files) /usr/local/Cellar/powervr-sdk/4.3/include/ (3 files) /usr/local/Cellar/powervr-sdk/4.3/lib/libEGL.dylib /usr/local/Cellar/powervr-sdk/4.3/lib/libGLESv1_CM.dylib /usr/local/Cellar/powervr-sdk/4.3/lib/libGLESv2.dylib /usr/local/Cellar/powervr-sdk/4.3/lib/libPVRScopeDeveloper.a $ otool -L /usr/local/Cellar/powervr-sdk/4.3/lib/libEGL.dylib /usr/local/Cellar/powervr-sdk/4.3/lib/libEGL.dylib: /usr/local/opt/powervr-sdk/lib/libEGL.dylib (compatibility version 0.0.0, current version 0.0.0) /System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices (compatibility version 1.0.0, current version 57.0.0) /System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 19.0.0) /System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0) /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 945.18.0) /usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0) /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 65.1.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0) /System/Library/Frameworks/AppKit.framework/Versions/C/AppKit (compatibility version 45.0.0, current version 1187.39.0)
ただし、あくまでもエミュレーションであり、ハードウェアアクセラレーションはありません。
Vulkanのヘッダーもありますが、本当に使えるんでしょうか?
PowerVR-sdkの中には他にもMakefileが何個かあって、Linux用と書かれてはいるのですが、*.makというマクロファイルを読み込むようになっていて、この*.makファイルが実はWindows用のnmakeというプログラムでしか利用できない代物で、っていうことはWindows上で開発してクロスコンパイルしているのだろうか。どちらにせよ、Macではどうしようもない。
2017.11/15 追記
さらに、egl.pcを作成してしまうことにしました。

個人的な使用感の問題で、MoltenVkとMoltenGLのインストール先を分けたかったので、分割しました。
MoltenVKはGLFWが次期versionでのサポートを表明していますが、MoltenGLは何の話も聞きませんねえ。
このEGLおよびGLESv2はMoltenGL専用であり、OpenGLでは使用できません。

今度こそほんまもんのgleである。

たまたまgleの official site をみたら Github にソースコードのレポジトリーを移動したとのことなので、早速 issue へクレームを書き込んだら、PR作ってくれと言われ、仕方なくPRを出したら、ものの2分も経たないうちに即効マージされたでござる。
「Win32でテストしてませんよ」って書いておいたのだが、「自分もWindowsのことはわからん。だが、だめだったら報告が来るだろうからその時に対応すればいい」とのこと。そんなヤバゲでアレゲな方針でいいのか。
さらにautoreconfした時のバグを教えてあげたら、キレ気味に「autotoolsなんか使っている人が何人居るんだ」と開き直ったので「じゃあ何でそんな機能作り込んであるんだよ」と言いたかったけど大人の対応したら、その日のうちに指摘した部分を直してやがった。もうあんまり関わらんでおこう。
2017.11/12 追記
OpenGL Frameworkとリンクしているのに、install nameにOpenGL Frameworkの名前がないという不具合を解消しました。

また新規のHomebrewのScriptを作ったのですが、テストを作るのが面倒でPRは出しません。
ていうか、実際にインストールされるファイルは1つだけというヘンテコで微妙なものだからです。
Project description
-------------------
Currently the project provides only a pkg-config [.pc] file, pthread-stubs.pc.
The latter contains the Cflags/Libs flags applicable to programs/libraries
that use only lightweight pthread API. See the next sections for the reasoning
and implementation details.
これのテストって言われても、何をすれば良いのやら。
ただし、効力はかなり強く、C++11を指定しないとbuild出来なかったいくつかのパッケージにおいて、stdを指定しなくともbuild出来るようになったパッケージがあります。あくまで、そのパッケージがあらかじめlibpthread-stubsに対応していた場合のみですが。
The following script installs libpthread-stubs on OSX with Homebrew.

現在わかっている問題は、これが存在している時にcairoを"--enable-vg=yes"を付けてビルドするとコンパイルエラーで止まってしまう。これはAmanithVG-sdkが悪い訳ではなく、本家(?)ShivavgのlibOpenVGを使っても同じこととなる。cairo側の問題。

endbinutils with GAS and GPROF
またもやHomebrewにPRが却下されたでござる。今回の却下理由は意味不明過ぎて、呆れてものも言えない。
そもそもの発端は、vulkan-sdkというものをビルドしようとしたところcmakeから「GASが見つからない。あったほうが良い」的なことを言われたため。それで、調べたところ本来GASはGNUのbinutilsというパッケージに含まれていることがわかったので、Homebrewでbinutilsを入れたところ、肝心なGASが入っていないため、binutilsのFormulaを、GASとついでにGPROFもインストールできるように改良して、HomebrewにPRを出したところ、「デフォルトでインストールされないものだから必要ない」という謎理由で却下された。お前が要らなくてもGASが必要な人は居るだろうに。
で、vulkan-sdkのほうはC++のヘッダーファイル(vk_loader_platform.h)を書き直さなければならないことが分かったので諦めました。
The following script installs GAS(from GNU binutils) on OSX with Homebrew. This script passed official Jenkins's test on Github.
