We are core profile now, no need to link against GLU.
This change makes it so Blender binary is not dependent on liGLU.so.
That was a weird thing that Blender was dependent on it, but was not
using any functions from it.
Prefer legacy OpenGL library, for the compatibility and portability
reasons.
Also use proper OpenGL libraries to be linked against, so we can
change preference to GLVND.
This commit makes it so that subsurf/multires modifiers will respect
the WITH_OPENSUBDIV option. The WITH_OPENSUBDIV_MODIFIER option is
now gone.
For artists it mean that subsurf modifier will behave same as it is
planned for 2.80. Multires will now support sculpting, but it has some
known limitations. Those will be worked on before the final release.
If OpenSubdiv is disabled, no subsurf/multires functionality will
present.
For the details see:

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).

The option WITH_C11 is gone, and C++ is defaulting to C++11 now,
so guess it's fine to assume we need C11 now.
This is technically what we use anyway, with all the re-definitions
of structs (like when we typedef anonymous struct in a header file
first, and them define it to a proper structure in implementation
file).
* 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.

Building the CUDA kernels takes quite a bit of memory, and when building all of
them the combined usage can be too much on some systems (especially VMs).
Therefore, this patch adds an option to force the build system to build them
sequentially by making each build step depend on the previous kernel.

For users it defines how accurate vertex positions are in terms
of limit surface (as in, how close the vertices locations to the
condition when they are calculated for an infinitely subdivided
mesh).
This affects things like:
- Irregular vertices (joint of 3 or more edges)
- Crease
Keep quality value low for performance.
NOTE: Going higher does not necessarily mean real improvement
in quality, ideal case might be reached well before maximum
quality of 10. Quality of 3 is a good starting point.
Internally quality is translated directly to adaptive subdivision
level.

This is in preparation of upgrading our library dependencies, some of which
need C++11. We already use C++11 in blender2.8 and for Windows and macOS, so
this just affects Linux.
On many distributions this will not require any changes, on some
install_deps.sh will need to be run again to rebuild libraries.

Previously CMake was raising a fatal error, which wasn't too helpful.
There is still some fatal messages about Audaspace and Game Engine,
but the latter one is on it's EOL and is removed in Blender 2.8.
Assert from BLI_assert by default in debug builds
(instead of just printing a warning).
Some developers ignored this, causing errors for others.
Better debug builds cause hard error so code isn't ignored.
Disabling is still useful when bisecting or testing outdated code.
Silences the following strict flags from external libraries:
- -Wclass-memaccess
- -Wswitch
- -Wtype-limits
- -Wint-in-bool-context
Needed to tweak macro a bit, since the old logic was wrong:
we can not use CXX flags for C compiler, need way more strict
separation between what goes where.
