Make very explicit what the tool does with CMakeLists about cpp-dependencies HOT 3 OPEN

The tool does not actually read the cmakefile at all; it uses its presence to mark a folder as a component, and scans it to see whether it's a library or an executable (defaulting to a library if it doesn't find it). The rest of the cmakefiles are completely ignored.

You can try adding empty files called "CMakeLists.txt" in the folders of other components to make it see a component there, or using the "--infer" flag to make it think of each folder with some sources as a component.

One alternative could be to actually read cmakelists, but that would make the tool much more complicated, tie it into CMake for its function, and would probably be fairly fragile by itself.

That should be added to the documentation, this requires you to have the definition as library or executable inside the cmake file directly and not hidden between further includes. Furthermore it requires you to never defines multiple targets in a CmakeLists.txt. Doesn't sound problematic once I know, would just be nice to add documentation about the expected project layout.

Changed the description to updating the documentation; for some reason many people think it actually reads the CMakeLists. To be completed together with adding support for other "build-style files" that demarcate components.
