## 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`

#### Using cmake
The cmake build is mostly contributer maintained.
Due to the multitude of use cases this is maintained on a _best effort_ basis.
Pull requests are welcome.
