Aha! This actually proves my add_subdirectory() point where the added 
directory when processed becomes the CMAKE_CURRENT_SOURCE_DIR.

But if the files are scattered randomly in various 4 level directories, some 
files that may need to be used on a platforms, others than dont, then you 
already have a nightmare and using SET() just shows the nightmare. Try to 
describe in more detail your project structure and also the simplest solution 
you can think of (even that it doesn't work directly with cmake like you 
think of it).
