[CMake] Naive (stupid?) question

[Dominik Szczerba]

I am also sometimes surprised by the radius of needed re-compilation
in my complex project... I think CMake tries to be on the safe side
and just regenerates everything that might have been affected. One
such example will be recompilation of large project parts if you
modified some variables in the root CMakeLists.txt.
On the other hand, you may have twisted dependencies in your project
that you may want to clean up and separate.

Is there a way in cmake to understand why things happens? I mean which chain of dependencies causes a given action to be taken? It would be for me very interesting to understand something more about the dependencies in my project, to be able to reduce them. Thanks and best regards,
