[Bf-committers] How to tell cmake to use system glew

[Richard Shaw]

I'm trying to get my blender package for Fedora to meet the packaging
guidelines (which are quite extensive).

One of the things I'm fighting with is that building things in
statically should be avoided (like openCOLLADA).

The problem I'm fighting now is that Fedora provides a glew package
but I'm not sure how to make cmake use the system installation over
the extern/glew version.

When I look at the CMakeLists.txt I see that many of them have options
which I'm assuming can be set ON/OFF with a cmake option, but glew
does not seem to have an options.

I'm not a C programmer so please excuse me if I'm not using the
correct terminology.

Thanks,
Richard
