This is Ubuntu 20.04 LTS / x86_64 / gcc 9.3.0 here.
I have been trying to use the “Sourcetrail” source code explorer.
At startup, it generates 7 “Type: FATAL” errors when indexing the ROOT’s source code (see below).
It reports several missing “*.inc” files for several source code “Files” (and “Translation Units”, which, in some cases, are different from the reported source code “Files”).
I guess the problem is that CMake generates a “compile_commands.json” file in which it includes build commands for all these “Files” / “Translation Units”, but it then does not execute them at all (at least on Linux).
@Axel Would it be possible that you somehow prevent CMake from including these redundant “build commands” (at least on Linux)?
Or maybe you could provide dummy “*.inc” files (at least on Linux) so that the indexer feels happy.

BTW. In order to prevent indexer’s errors related to Fortran source code files (saying “expected a clang compiler command”), when creating a “New Project”, one needs to add a magic “**.f” entry (note the double “**”) in the “Excluded Files & Directories” box.
