Yes, I have this option "Schedule all project files for parsing" ON.
Though, there is an explanation of how it behaves when this option is
turned on it does not explain how it works when this option is turned off.
Which is more important, I guess. So I'd prefer to have this knowledge
before turning this off.

Well it is clear enough what files are part of the project: all files in
the source tree except the excluded ones. All known types like .c, .cpp and
.h are parsed. In that is equivalent CMake scheme, because CMakeLists.txt
contains the vary same file lists. I do have to add some preprocessor
variables manually though. But what else of "interdependencies" can be
important?

Precompiled headers not used.

I believe this is easily reproducible. You have all the knowledge what to
do and what sources to take. I can send you KDevelop project files.

No, as I expected nothing bad happens.
