Autocomplete in Qt Creator: how to add header files for a cmake project -

If I am creating a QT Creator project using CMake instead of QMK, then I can tell Qt Creator that Where to autocomplete headers files? In CMakeLists.txt, I can specify where to compile in the title, but the Qt Creator will not read it until I create this project.

You include the source files as well as the headers you add to the source list Adding them can show that this is a part of your project, it works for files.

For header files from anywhere on your system, where the compiler can find them, I thought running SIMKK (to generate makefiles) should be enough for QT to find the manufacturer.
