CMakeLists.txt files are not being shown from parent directories of main project

Given a fairly common directory structure:

repo_root

  Main

    CMakeLists.txt

  Common

    CMakeLists.txt

The CMakeList.txt under Main might acquire the one in Common via `add_subdirectory(../Common)`.

When Qt Creator 17 parses this it no longer lists the CMakeLists.txt files from those parent directories.

This has all kinds of consequences; e.g. not being included in searches.
