This is in preparation of an the upcoming fix where we need to use a Metal
layer to avoid performance issue when drawing with OpenGL. Note that we already
only officially support 10.12+, the difference with this change is that Blender
will not start at all on 10.9 and 10.10.
Two changes:
Removed the explicit version for the macOS SDK, recent
versions of Xcode have a symlink to the newest SDK.
Fixed the build script for OpenMP by removing extra ' marks that
install_name_tool took literally and replaced INSTALL_PATH with
INSTALL_DIR.
Note that this is turned off by default and must be enabled at build time with the CMake WITH_CYCLES_EMBREE flag.
Embree must be built as a static library with ray masking turned on, the `make deps` scripts have been updated accordingly.
There, Embree is off by default too and must be enabled with the WITH_EMBREE flag.
Using Embree allows for much faster rendering of deformation motion blur while reducing the memory footprint.
TODO: GPU implementation, deduplication of data, leveraging more of Embrees features (e.g. tessellation cache).

-expanded build_deps.cmd with 2017 support, it can't locate msvc2017 so needs to be run from developer prompt.
-Newer cmake was unhappy with openal's cmakelists.txt
-collada has warning as error on and errored out on new msvc2017 warnings.
FFMPEG & VPX don't handle target with --build parameter, so we need to make sure use of plain configure command

Note these are intended for platform maintainers, we do not intend to
support users making their own builds with these. For that precompiled
libraries from lib/ should be used.
Implemented by Martijn Berger, Ray Molenkamp and Brecht Van Lommel.
