Clang Code Model not working with Cmake precompiled headers

Qt Creators Clang Code Model, autocompletion and outline are working as long as precompiled headers have not been build. After build those functions are not working for all files that are newly opened in the text editor.

See the minimal sample project attached to reproduce:

1) Open project in Qt Creator

2) Do not open any files in the code text editor

3) Build the project

4) Open main.cpp in the code text editor

5) Autocomplete, Outline and Clang Code Model are not working

6) Close main.cpp code editor

7) Clean the project

6) Open main.cpp -> Autocomplete and Clang Code Model are working again

My Cmake version is 3.18.5
