Set up CMake in a "recursive fashion"

[mirestrepo]

I may be wrong, but I think it is more common to set up CMake in a "recursive fashion", so your root CMakeLists.txt has something like

add_subdirectory(src)

and each subdirectory has it's own CMakeList that includes another directory or the sources....

See these links:
https://cliutils.gitlab.io/modern-cmake/chapters/basics/structure.html
https://gitlab.com/CLIUtils/modern-cmake/-/blob/master/examples/extended-project/CMakeLists.txt

How do you feel about that organization?

I would have to re arrange the folder structure to create small components.
for example, taking the current folder structure as example:

• VR-VolumeViewer
  • src
    - VolumeVisualizationApp.cpp
  • include
    - VolumeVisualizationApp.h
  • libs
    • render
      • src
        • Volume.cpp
      • include
        • Volume.h
          - UI
      • src
        • UIView.cpp
          - include
        • UIView.h
