syntastic: include header files that are spread around in a large project

Question

I have a big C project with many software components around. The file tree has a root, say C:\MyProject\SoftwareComponents\ that contains a bunch of sub-folders which in turn contain some other sub-folders that contain .c and .h files. A sketch of such a file tree looks like this

C:\MyProject\SoftwareComponents\
                                 CompOne\
                                 Foo\
                                 Fii\
                                 ...
                                 Zooroo\ 

I am failing in setting the option let g:syntastic_c_include_dirs=... since I always get an error like: fatal error: xyz.h: No such file or directory. I tried to tweak Syntastic in many ways like

let g:syntastic_c_include_dirs = ['./../inc','./inc'] 
...

but this approach seems to heavily depend on pwd and it is not robust.

All the solutions that I found suggest to list the all components sub-folders one-by-one in let g:syntastic_c_include_dirs where you may possibly have some .h file but for my case it is very inefficient as I have way too many software components and listing each folder one-by-one is impossible.

I thought that one may use some wildcard, e.g. let g:syntastic_c_include_dirs = ['C:\MyProject\SoftwareComponents\**'] but it does not work.
