If you have a directory structure with multiple levels, say
source
source/Graphics
source/Graphics/Camera
source/Graphics/Camera/Orthographic
source/math
source/math/matrices
source/network
How can you isntruct Cmake to travle through the full subdirectory tree and include every single cpp file found?
i.e
target_sources(voxel-cone-tracing PUBLIC <All sources go here>)
