Default configuration already includes libmv and glog, so all
the dependencies are met. And logging is nice to have anyway.
This wouldn't give any slowdown, because all the logging is
silenced unless '--debug-cycles', plus no logging is done
from the speed critical code.
This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.
We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.

Currently only summed number of traversal steps and intersections used by the
camera ray intersection pass is implemented, but in the future we will support
more debug passes which would help checking what things makes the scene slow.
Example of such extra passes could be number of bounces, time spent on the
shader tree evaluation and so.
Implementation from the Cycles side is pretty much straightforward, could only
mention here that it's a build-time option disabled by default.
From the blender side it's implemented as a PASS_DEBUG with several subtypes
possible. This way we don't need to create an extra DNA pass type for each of
the debug passes, saving us a bits.

This commit makes it possible to use Glog library for the debug logging.
For now only possible when using CMake and in order to use the logging
the WITH_CYCLES_LOGGING configuration variable is to be enabled.
When this option is not enabled or when using Scons there's no difference
in Cycles behavior at all, when using logging and no output to the console
impact is gonna to be minimal.
This is done in order to make it possible to have debug logging persistent
in code (without need to add it when troubleshooting some bug and removing
it afterwards).
For now actual logging is not placed yet, only all the functions needed for
the logging are written and so.
This solves missing requests package reported on the systems where it's
located in dist-packages rather than in site-packages.
To do this there's now a helper macros which handles both requests and
numpy now and could be used for more packages in the future.

- this workaround makes sure the breaking -fopenmp is not exposed to testcompiles which use C_FLAGS respective CXX_Flags
- -fopenmp is always added to the CMAKE_C(XX)_FLAGS_<BUILD_TYPE> now
- another way to solve this would be to move the Configure OpenMP part after all line 2366,
but i don’t know if this would be apreciated
- test fail due libiomp5 is not available @ testing time
- must solve this by adding requred flags/includes to tests
- atm release builds are possible with this hack
This reverts commit da7bdf1b47d4490c1a6f35740a9392cb9b5dd42e.
This broke compilation in OSX and some Linux boxes.
Error: Policy "CMP0043" is not known to this version of CMake
Shall we leave those for after RC (or even 2.71) is out? ;)
next time you're deprecating some platform, compiler, feature just either
mail in the ML telling about this or if you're not that lazy poke developers
online whether then can spot issues quick.
Or be ready to pick up stuff being done by the developers your change gives
headache to.
This also updates the configurations to build kernels for compute capability
5.0 cards, when using and older CUDA toolkit version this will be skipped.
Also includes tweaks to improve performance with this version:
* Increase max registers on sm_30, sm_35 and sm_50
* No longer use texture storage on sm_30
This is done in SCons and the only reason to disable OpenMP on
Windows was to deal with the express version of compilers.
Now when we are about to switch to msvc2013 by default we can
safely enable OpenMP there since even express version of this
beast supports OpenMP.
Fixes T39423: Blender crashes on iv41 encoded videos in thumbnail display mode
Libraries are still being committed to the svn, so compilation might be broken
for a while. Sorry for this, but can't really be avoided.
Also, some typos in scons are possible.
Some int/float conversion warnings were disabled by buildsystems but
re-enabled by BLI_winstuff.h, the warnigns relate to conversions not
considered issues on other systems so better just quiet them.
