[C++] Error making the cpprestsdk generated files

[mull]

Description

After using the generator as described for cpp-restsdk and trying to make the project, I receive a bunch of errors. (I've been trying all day and only now realised that either I'm doing something really wrong, or the generated code is broken.)

I see the following errors:

I might be using the lib wrong... the sample for cpp-restsdk is broken :|

@mull
The sample is compiling. I just tested it. You might want to use the latest master snapshot as well to check.

Regarding the oneOf I think we have an open bug for it.

We have an issue we need to work on for all C++ generators.
#6378

In the end it's about oneOf and these things. Using the spec that I linked to it'll produce stuff like

#include "OneOfnumberarray.h"
#include "OneOfstringarray.h"

Which are files that don't exist (or are not provided, at least.) I give up for now, but I'll follow that issue. Thanks!
