[Bf-committers] Propose to reduce default feature set (*nix dev builds)

[Martijn Berger]

Hi,

@Terry, I would like to point out that most developers I know already build
with a very very reduced feature set anyway.
Blender in general is ridiculously difficult to build if only as a result
of its large number of dependencies and things like boost/C++ ABI stuff
adding to that.

I think OpenEXR and Ilmbase libs should maybe not be disabled by default as
it is the highest fidelity output format and not *that* bad compared with
the rest of the list.

I would disable by default:

   - WITH_OPENCOLLADA
   - WITH_OPENCOLORIO
   - WITH_CYCLES_OSL
   - WITH_CODEC_FFMPEG
   - WITH_SDL
   - WITH_NDOF
   - WITH_BUILDINFO
   - WITH_GAMEENGINE
   - WITH_JACK
   - WITH_IMAGE_REDCODE
   - WITH_IMAGE_PSD

Maybe it would be good to also have the opposite WITH_FULL_RELEASE_BUILD
that just enables all this and is not cached ?
