How to build and configure a distribution from a bunch of disparate files?

Question

Qt

There is a rather large project in C++/Qt/qbs under Win32 that is built using TeamCity.
Used by qbs and its tools, the build results after qbs install end up in a structured folder , almost ready to be slipped into Inno Setup.
But besides the build results (binaries, translations), there are also a bunch of files for the interface (qml, js), ini project settings files for a specific configuration. The total number of such files can reach 300-500.
Now a bicycle has been written in C - a utility that builds the distribution structure based on the xml description of a specific software configuration (there are about 12 configurations themselves).
The utility performs the following tasks:

• Copying files and/or folders to a specific location (masks with exceptions are supported)
  
• Operation with settings in ini files in the destination folder
  
• The ability to build a chain of configuration description xml files to avoid duplication of common pieces
  
• Calling some other utilities to perform intermediate operations (for example, signing binaries with a certificate)
  

Can you please let me know if there is any tool for this task?
It is clear that you can write a bunch of code in powershell / js / c ++, but this is already like from hopelessness. Then IMHO it is better to use your bike, especially since he already has one.
The current bike as a whole suits, perhaps with the exception of the inability to parallelize the assembly of individual configurations.
Now a lot of different new assembly tools appear, and I want to know how experienced comrades solve such problems.
