    Description

      If your CMake projects uses nested projects (e.g. to be able to build all parts individually but also have a way to build them all combined), the QML Compiler statistics doesn't show all QML modules.

      In the attached example a toplevel project adds two sub-projects, each subproject contains a QML module.
      The QML module uses qmlsc to compile it to C++ code as you can see by running `ninja -v`

      Running the `all_aostats" target only shows one of the modules:
