OpenGLES

1. ES is embedded version, subset of GL, mostly for Android/Mobile

2. Simulator on Windows 

  Windows prefers DirectX instead OpenGL, by default, only OpenGL1.1 dll is distributed in Windows OS. The latest version of OpenGL/2021 is 4.5 now.

   Prefer ARM mali ES simuator on Windows
 Qualcomm OpenGL ES 3.0 Emulator, ARM OpenGL ES 3.0 Emulator, and PowerVR OpenGL ES 3.0 Emulator

2. Google ANGLE binary for Windows (Almost native!!)
2.1 Google Chrome Browser 
   ANGLE is part of Chrome browser.  Copy from chrome is fine!!

 Google ANGLE project (for WebGL through hardware rendering via Windows D3D9/D3D11) .  https://chromium.googlesource.com/angle/angle/+/main/README.md
  Note WebGL is also based on OpenGL ES (2.0)

2.2 QT Windows Release
 
2.3 VSCode 
 VSCode has libGLESv2.dll which will call directX(d3d9.dll). these files are from Googl ANGLE project.  Refer to dll/detail info

3. MSYS2/Windows/OpenGL1.x 

$ pacman -S mingw-w64-x86_64-freeglut
$ pacman -S mingw-w64-x86_64-glew

gcc -lfreeglut -lglew32 -lopengl32

--->  
MinGW comes without "an OpenGL", your operating system (the graphics card driver, usually) provides OpenGL.

MinGW provides a header file (gl.h), and a corresponding library (libopengl32.a) which is a wrapper for opengl32.dll, a dynamic library which comes with Windows and contains the handles to OpenGL 1.0 an 1.1 functions... something around that, not sure about exact version numbers.

Refer to msys64\mingw32\i686-w64-mingw32\include\GL\gl.h
     msys64\mingw64\x86_64-w64-mingw32\include\GL\gl.h

4.   Header files for EGL/OpenGL ES 

You also need the EGL and OpenGL ES headers, which should be included in the SDK. 
The latest version can always be obtained via the Khronos API registry for EGL (https://www.khronos.org/registry/egl/) and OpenGL ES (https://www.khronos.org/registry/gles/#headers31).
