Building library fails on cmake and Makefile

[grahamreeds]

I have tried building with master branch and the source given in the 2.2.0 zip file. Both exhibit the same behaviour.

You freely admit that the CMake version is user-maintained but as that is what I use I will begin with that.

Attempting to compile with that gives the following output:

/workspaces/glew-2.2.0/build $ cmake ./cmake

CMake Generate step failed.  Build files cannot be regenerated correctly.

And for calling makefile:

/workspaces/glew-2.2.0 $ make
/bin/sh: 1: config/config.guess: Permission denied
/bin/sh: 1: config/config.guess: Permission denied
Makefile:40: *** "Platform '' not supported".  Stop.
/workspaces/glew-2.2.0 $

I might be able to pass this by adding sudo but I shouldn't have to - why does the compile need super user rights?

Hello @grahamreeds

Unless you want to contribute to GLEW it's recommended to build from an official release:
https://glew.sourceforge.net/

See #13 for more details.

I would just like to pull it into my projects, which are all CMake based, and as part of the build. Manual steps outside the main build is a non-no as that (in my experience) have people scratching their heads and disturbing other members of the team as to what went wrong. Making it as fool proof as possible is key.

I will look to see if there is a simple CMake command to download a zip and extract.

I'd recommend Perlmint/glew-cmake for that use case.
This repo is less focused on cmake.
