WITH_ASSERT_ABORT was not disabled for release builds. In most cases asserts
are disabled in release builds, but not always.
This also changes the buildbot to use blender_release.cmake instead of
blender_full.cmake, the only effective difference should be WITH_ASSERT_ABORT.
- Foe some reason CMake's platform and processor are not intialized there.
- Need to set variables in cache, otherwise they are not visible in the
actual CMake files.
This will respect the official build configuration where we should
have BLOSC enabled.
We can't really detect if OpenVDB was compiled with BLOSC or not,
so seems we can't really avoid this extra flag.
This is so called "seems to work in dry tests" commit which is aimed to switch
linux release environment to CMake.
Some notes:
- There's no special handle of libstdc++, but it wasn't really static for quite
some time in SCons configuration and nobody really complained.
- It was quite tricky to get OpenMP linked statically with just using some
configuration so we went ahead and added a special option to CMake now which is
only exist on Linux and advertised as shouldn't be used.
- Packing is happening manually in slave_pack.py. This is because we have to add
some really special files to the archive (mesa libraries for example) which we
can't really handle from CMake/CPack in a nice generic way.
Don't think it's bad approach, at least crappynness is localized and it's not
_that_ crappy anyway.
- Windows buildbot should keep working, but needs doublechecing. It's just a
build folder changed, but you never know what it might imply.
- Some further tweaks are likely needed to ensure all builders are working.
Thanks Campbell for assistance in this patch!
