Based on D2578, now you can install JACK audio server and use it in
Blender build without having to specify the `--with-all` option (that
one still enables also JACK of course).

Couple of things here:
- Boost is not necesserily compiled into your /opt/lib and system-wide
version might have been used. The recent change in Alembic did not
take this into account.
- Alembic needs some extra component of Boost.
This part might be missing now for other distros than DEB.
This provides us with a clearer API (so I don't have to use const_cast<>
in upcoming code). It also allows layering of different Alembic files,
so you can have a base file and load a separate file containing overrides.
Verbally approved by Dr. Sergey.
Alembic requires one of ALEMBIC_LIB_USES_BOOST, ALEMBIC_LIB_USES_TR1, or
C++11, and silently defaults to the latter if the former two are OFF.
Before this change, Alembic was only built without C++11 of OpenEXR
was built at the same time. This dependency was both unnecessary and
undocumented.
For now, we merely add an option that sets CXXFLAGS envvar with
'--std=c++11' option.
There is no check done to ensure compatibility with the system
libraries, mainly because:
- It is all but trivial to get this information in a generic and
reliable way.
- Currently even cutting edge distributions may still distribute some c++98
libraries.
- With recent stdlibc++, both ABIs are supported together, which means
that incompatibilities are rather unlikely.
To summarize: if your system is recent and built with gcc-5.1 or more,
you should not experience too much troubles with c++11.
All in all, this patch adds an Alembic importer, an Alembic exporter,
and a new CacheFile data block which, for now, wraps around an Alembic
archive. This data block is made available through a new modifier ("Mesh
Sequence Cache") as well as a new constraint ("Transform Cache") to
somewhat properly support respectively geometric and transformation data
streaming from alembic caches.
A more in-depth documentation is to be found on the wiki, as well as a
guide to compile alembic: https://wiki.blender.org/index.php/

Many thanks to everyone involved in this little project, and huge shout
out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini
and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the
custom builds and compile fixes.
