CMake 2.8 doesn't search /usr/include/SDL2, which is the include directory
for SDL 2.x on Ubuntu Linux (and possibly others). This results in SDL 1.2
headers being found when WITH_SDL_DYNLOAD=OFF, and our shipped SDL 2.0
headers when WITH_SDL_DYNLOAD=ON. This patch ensures that in both
cases the correct SDL headers are used.

Doesn't mean we're 100% ready for the transition, but need to start somewhere
anyway. Changes:
- OSL is no longer supporting cpp and requires usage of Boost Wave.
So now Wave component of Boost is optionally demanded when looking for the
Boost libraries if OSL is enabled.
Only did this for Linux, MSVC seems already using Wave. Not sure about OSX.
- Because of the same reason OSL should be moved prior Boost for linker.
- Whole archive trick makes it so linking fails with duplicated symbols, so
removed it for the new OSL. Didn't see issues with this so far.
- Added some code to check OSL version on Linux. Would need to move all that
to FindOpenShadingLanguage.cmake which we can get from Cycles standalone
repository.
So in theory no affect on current stup would be made at all.
- Added some tweaks to buildbot files. It now seems to be happy with the new
OSL libraries, but again, those tweaks are not in action yet.
All this was tested on Linux only. Win/OSX might still need some tweaks to
support new OSL.
P.S. This doesn't mean we're pushing OSL update yet, just making some
preliminary tweaks to avoid entropy of PITA when we'll actually want to
switch.
code.
The implicit solver itself should remain agnostic to the specifics of
the Blender data (cloth vs. hair). This way we could avoid the bloated
data conversion chain from particles/hair to derived mesh to cloth
modifier to implicit solver data and back. Every step in this chain adds
overhead as well as rounding errors and a possibility for bugs, not to
speak of making the code horribly complicated.
The new subfolder is named "physics" since it should be the start of a
somewhat "unified" physics systems combining all the various solvers in
the same place and managing things like synchronized time steps.
Generally for build systems, libraries that do not depend on other
libraries, such as system libraries, OpenGL etc always go at the end.
We could even get rid of some duplicate dependency libraries here but
auto duplication by build systems and differences between OSs make this
difficult.
GTest still duplicates all libraries twice to solve some issues which is
weird (maybe libs are not sorted correctly for some reason? needs
investigation)
This commit contains all the tweaks which were missing in initial patch
re-integration from the standalone Cycles repository.
This commit also contains an utility cmake macro to help linking targets
with different libraries for release/debug builds, the name currently is
target_link_libraries_decoupled
it gets a target and list of libraries and makes sure debug builds are
using libraries with "_d" suffix.
After all this changes it'll hopefully be easier to interchange patches
between blender and standalone repositories, because they're now quite
identical.
Basic idea is to check whether OIIO is compiled with embedded PugiXML parser
and if so use PugiXML from OIIO, otherwise find a standalone PugiXML library.
Either ./blender-git or ~/blender-git should be used, but not
.~/blender-git. This patch fixes that, by choosing ~/blender-git,
in line with the last CLI argument.
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.

For now it was mainly about OpenCL wrangler being duplicated
between Cycles and Compositor, but with OpenSubdiv work those
wranglers were gonna to be duplicated just once again.
This commit makes it so Cycles and Compositor uses wranglers
from this repositories:
- https://github.com/CudaWrangler/cuew
- https://github.com/OpenCLWrangler/clew
This repositories are based on the wranglers we used before
and they'll be likely continued maintaining by us plus some
more players in the market.
Pretty much straightforward change with some tricks in the
CMake/SCons to make this libs being passed to the linker
after all other libraries in order to make OpenSubdiv linked
against those wranglers in the future.
For those who're worrying about Cycles being less standalone,
it's not truth, it's rather more flexible now and in the future
different wranglers might be used in Cycles. For now it'll
just mean those libs would need to be put into Cycles repository
together with some other libs from Blender such as mikkspace.
This is mainly platform maintenance commit, should not be any
changes to the user space.
