+# GLEW - The OpenGL Extension Wrangler Library
+
+The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems, including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.

+### Recent snapshots
+
+Snapshots may contain new features, bug-fixes or new OpenGL extensions ahead of tested, official releases.
+
+[glew-20220402.tgz](https://sourceforge.net/projects/glew/files/glew/snapshots/glew-20220402.tgz/download) *GLEW 2.2.0 - with fix for glCreateProgressFenceNVX*
+
+## Build
+
+It is highly recommended to build from a tgz or zip release snapshot.
+The code generation workflow is a complex brew of gnu make, perl and python, that works best on Linux or Mac.
+The code generation is known to work on Windows using [MSYS2](https://www.msys2.org/).
+For most end-users of GLEW the official releases are the best choice, with first class support.
+
+### Linux and Mac
+
+#### Using GNU Make
+
+GNU make is the primary build system for GLEW, historically.
+It includes targets for building the sources and headers, for maintenance purposes.
+
+##### Install build tools
+
+Debian/Ubuntu/Mint:    `$ sudo apt-get install build-essential libxmu-dev libxi-dev libgl-dev`
+
+RedHat/CentOS/Fedora:  `$ sudo yum install libXmu-devel libXi-devel libGL-devel`
+
+FreeBSD: `# pkg install xorg lang/gcc git cmake gmake bash python perl5`
+
+##### Build
+
+	$ make
+	$ sudo make install
+	$ make clean
+
+Targets:    `all, glew.lib (sub-targets: glew.lib.shared, glew.lib.static), glew.bin, clean, install, uninstall`
+
+Variables:  `SYSTEM=linux-clang, GLEW_DEST=/usr/local, STRIP=`
+
+_Note: you may need to call `make` in the  **auto** folder first_
+
+##### Linux EGL
+
+	$ sudo apt install libegl1-mesa-dev
+	$ make SYSTEM=linux-egl
+
+##### Linux OSMesa
+
+	$ sudo apt install libosmesa-dev
+	$ make SYSTEM=linux-osmesa
+
+##### Linux mingw-w64
+
+	$ sudo apt install mingw-w64
+	$ make SYSTEM=linux-mingw32
+	$ make SYSTEM=linux-mingw64
+
+#### Using cmake
+
+The cmake build is mostly contributor maintained.
+Due to the multitude of use cases this is maintained on a _best effort_ basis.
+Pull requests are welcome.
+
+*CMake 3.16 or higher is required.*
+
+##### Install build tools
+
+Debian/Ubuntu/Mint:   `$ sudo apt-get install build-essential libxmu-dev libxi-dev libgl-dev cmake git`

+## Code Generation
+
+A Unix or Mac environment is needed for building GLEW from scratch to
+include new extensions, or customize the code generation. The extension
+data is regenerated from the top level source directory with:
+
+	make extensions
+
+An alternative to generating the GLEW sources from scratch is to
+download a pre-generated (unsupported) snapshot:
+
+https://sourceforge.net/projects/glew/files/glew/snapshots/
+
+## Authors
+
+GLEW is currently maintained by [Nigel Stewart](https://github.com/nigels-com)
+with bug fixes, new OpenGL extension support and new releases.
+
+GLEW was developed by [Milan Ikits](http://www.cs.utah.edu/~ikits/)
+and [Marcelo Magallon](http://wwwvis.informatik.uni-stuttgart.de/~magallon/).
+Aaron Lefohn, Joe Kniss, and Chris Wyman were the first users and also
+assisted with the design and debugging process.
+
+The acronym GLEW originates from Aaron Lefohn.
+Pasi K&auml;rkk&auml;inen identified and fixed several problems with
+GLX and SDL.  Nate Robins created the `wglinfo` utility, to
+which modifications were made by Michael Wimmer.
+
+## Contributions
+
+GLEW welcomes community contributions.  Typically these are co-ordinated
+via [Issues](https://github.com/nigels-com/glew/issues) or
+[Pull Requests](https://github.com/nigels-com/glew/pulls) in the
+GitHub web interface.
+
+Be sure to mention platform and compiler toolchain details when filing
+a bug report.  The output of `glewinfo` can be quite useful for discussion
+also.
+
+Generally GLEW is usually released once a year, around the time of the Siggraph
+computer graphics conference.  If you're not using the current release
+version of GLEW, be sure to check if the issue or bug is fixed there.
