I have the same problem on MacOS but this seems not coming from CMake but from the last version of QT Creator 4.11.x I installed an instance of Qt Creator to 4.10.x and get back project structure as folders structure.

I was just mentioning that's how the video demonstrated. Thanks to you I have the files in my test project and they are the files from my actual app, now compiling seems to be the issue. I had a couple things to do to get it build able again but now I can at least compile my c++ classes. I have one test with one of my objects now so thanks.

You can set Project A.3 (subdirs) to depend on Project A.1 (subdirs) of course this create a problem if Project A.1.2 (app) depends on Project A.3.1 (lib)

Hi and welcome to devnet, Can you compare that with a pre 4.0 version of Qt Creator ?
