Why exactly has the LablGL and other commonly used utilities ceased to support the newest versions of Ocaml?
(4.0.3 cannot compile it due to the lack of camlp4 support)
Is there any reason other than loss of interest that they have ceased to be maintained?
And are there any alternatives that are available that work now?

I'm not sure what your problem is exactly doing an opam install lablgl with OCaml 4.01.0 works fine here.
That said if you are interested in a more direct and recent, but less safe, interface to OpenGL you can have a look at tgls.

Some libraries, such as LLVM, use a "superproject" pattern, where consumers of the library, such as libcxx, should live inside of the libraries' folder-structure. In the case of LLVM, this is llvm/projects.
This seems quite limiting, as it makes it harder use the library when there are other folder-structure constraints.
Why was this descision made, and what are some reasons to use such a layout?

I am in an environment which has no C++ compiler software installed, and I was wondering if it was possible for me to compile C++ code without having to install anything.
From within PS run help add-type -full and look for the F# example (example 7 on my system). Assuming you have a C++ compiler that follows the "CodeDom" model, you can mirror the F# example.
Of the two alternatives you gave, I'm going to go with "blindly obvious"

I remember a while ago I heard that there were thoughts of including a BigInteger implementation in the c++0x standard(as it was called back then). Apparently this did not happen but I was wondering if this is planned as part of c++1y or not.
The unbounded integer library is being worked on in SG6, the Numerics study group. It will probably go into a Technical Specification (TS, what used to be called a TR) once we sort out a few things about its interface and about interoperability of library numeric types.
The latest official paper on the subject is N3542. It is not slated for inclusion in C++14.

I am wondering if -Dfoobar the standard way for adding definition to the compiler for all the C++ compiler.
-Dfoobar works for all the compilers that have ever been used to compile Firefox, which is good enough for me. The Microsoft compilers also accept /Dfoobar, of course.

What are the advantages of C++ over the others languages in working with videodata and videodevices (developing object detection program). Thank you.
for object detection, you could use python, matlab, java and c++. You have to use c++ if you need substantially speed improvement (C++ is the fastest in most of the cases). You could also use OpenCv easily with c++ for face and object detection.
