##### Build
$ cd build
$ cmake ./cmake
$ make -j4
| Target | Description |
| ---------- | ----------- |
| glew | Build the glew shared library. |
| glew_s | Build the glew static library. |
| glewinfo | Build the `glewinfo` executable (requires `BUILD_UTILS` to be `ON`). |
| visualinfo | Build the `visualinfo` executable (requires `BUILD_UTILS` to be `ON`). |
| install | Install all enabled targets into `CMAKE_INSTALL_PREFIX`. |
| clean | Clean up build artifacts. |
| all | Build all enabled targets (default target). |
| Variables | Description |
| --------------- | ----------- |
| BUILD_UTILS | Build the `glewinfo` and `visualinfo` executables. |
| GLEW_REGAL | Build in Regal mode. |
| GLEW_OSMESA | Build in off-screen Mesa mode. |
| BUILD_FRAMEWORK | Build as MacOSX Framework. Setting `CMAKE_INSTALL_PREFIX` to `/Library/Frameworks` is recommended. |
### Windows
#### Visual Studio
Use the provided Visual Studio project file in build/vc12/
Projects for vc6 and vc10 are also provided
#### MSYS/Mingw
Available from [Mingw](http://www.mingw.org/)
Requirements: bash, make, gcc
$ mingw32-make
$ mingw32-make install
$ mingw32-make install.all
Alternative toolchain: `SYSTEM=mingw-win32`
#### MSYS2/Mingw-w64

Alternative toolchain: `SYSTEM=msys, SYSTEM=msys-win32, SYSTEM=msys-win64`
## glewinfo
`glewinfo` is a command-line tool useful for inspecting the capabilities of an
OpenGL implementation and GLEW support for that. Please include the output of
`glewinfo` with bug reports, as appropriate.

## Code Generation
A Unix or Mac environment is neded 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/
Travis-built snapshots are also available:
https://glew.s3.amazonaws.com/index.html
## 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 Kärkkäinen identified and fixed several problems with
GLX and SDL. Nate Robins created the `wglinfo` utility, to
which modifications were made by Michael Wimmer.
## Copyright and Licensing

GLEW - The OpenGL Extension Wrangler Library
http://glew.sourceforge.net/
https://github.com/nigels-com/glew
See doc/index.html for more information.
If you downloaded the tarball from the GLEW website, you just need to:
Unix:
make
sudo -s
make install
make clean
Windows:
use the project file in build/vc12/
If you wish to build GLEW from scratch (update the extension data from
the net or add your own extension information), you need a Unix
environment (including wget, perl, and GNU make). 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/
Major:
- add support for windows mini-client drivers
- add windows installer (msi)
- separate build of static and shared object files (for mingw and
cygwin)
- start designing GLEW 2.0
Minor:
- make auto scripts work with text mode cygwin mounts
- add support for all SUN, MTX, and OML extensions
- make auto/Makefile more robust against auto/core/*~ mistakes
- web poll on separating glew, glxew and wglew
