Cherry pick source code on lib_deps

Hi there
I try to use the qpc framework in (quantumleaps/qpc@^6.3.7) my project. The build machine just compiles all the code in src folder of the Library - regardless of any side conditions. In the final build only a selected part (cherry-picked part) of all source code should be included in the Binary. Depending on the project configuration this would result in a other Running Program.

A striped down version of my project can be found on my github:

I think it is not an easy task to understand what QPC is, but the Book is worth reading. The reference is:


Fork and put a library.json in it with srcFilter expressions to filter out source files you don’t like, or add a script that dynamically turns on the subframeworks.
