weird cmake structure in this project

[MasakatsuFunaki]

Best practice is to have one CMakeFilelist.txt per folder . This project uses a root cmake from which everything is added , like exes , shared libraries etc . This is terrible idea and contradict with the basic principle of sw development called partitioning or decomposition.
I thought this was a well defined project

Having one CML file per directory is dogmatic. The only time when it makes sense is if you are used to make style in-source builds squirting build artifacts all over the source directory, but that's already very bad practice (in-source builds), so with that gone having a CML in every directory loses its purpose.

The project generates a flat structure for the simple case, which can be tweaked freely in any fashion. Tests for example are already separated where possible (library projects).
