That's what I'm trying to tell you: Any C++ build process that goes 
simple "hello world!"-like programs probably cannot be managed by 
machines only.

There is a whole lot of stuff build system does in C++. It defines the 
way the structure of
the project goes and the way files include or use other files. Some 
source files are generated
by the build system. In C++ there is no standard how to include files, 
unlike in Java.
Also, the build system must perform a series of checks on the compiler,
the envinronment, libraries, et cetera. _Especially_ if you want 
cross-platform code.

Essentially, the build scripts are part of the source code.

First of all, you don't only require the QtC to _parse_ the build 
you require QtC to _understand_ the code completely.

Second, it indeed might be possible for QtC to parse and (to some 
extent) "understand"
build scripts, but it is an enourmous effort and most importantly, 
pointless effort,
because most developers are just fine writing their own script.

I personally would not entrust any software to automatize the task for 

It would basically be like having your website generated by MS 
FrontPage ;-)
