llvm generates some header files at build time that differ between
debug/release causing linker errors when you used the release headers
for a debug build.
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.
This bring macOS on par with Windows and Linux. It uses the OpenMP library
added to our precompiled libraries.
Custom flags are set because FindOpenMP from CMake below 3.12 does not support
AppleClang, and more recent versions do not work with our custom directory
location either.

Now, things are becoming REALLY confusing. The script does build
pugi, but is never telling OIIO to use an external one. Which makes
it to use a bundled one.
Trying to link OSL to a different version of pugi causes a lot of
linking errors.
Interestingly enough, that was me who made OSL to use external pugi
to solve configuration problem. But now i can not reproduce that
anymore.
Ideally we would either link everything against our pugi, or not
compile it at all.
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).

ffi stubbornly wants to put libs in lib64 even when you tell it not to on some linux distributions.
patch based on sed fix the gentoo guys did [1]

Since we are not linking against OpenCV ourselves, that generated
linking errors later on (while building OSL e.g.).
Those 'open' libs link against way too many other libs... :/
Thanks to @intrah for initial report (T56785), and @LazyDodo for
suggested solution.
* WITH_SYSTEM_OPENJPEG is removed and is now always on, this was already
the case for macOS and Windows.
* This should not break existing Linx builds. If there is no new enough
OpenJPEG installed, CMake will no find libopenjp2 and WITH_IMAGE_OPENJPEG
will be disabled.
* install_deps.sh was updated with new package names, since distributions
put this version in a new package.

Mainly this is following Linux to build own xml2/lzma/ssl/sqlite and linking
them all statically. This ensures the Python ssl module uses a recent openssl
version rather than a very old one shipped with macOS.
