Src_filter = -<src/> +<other_folder/> not taken into account

Per docs

PATH is relative to src_dir

So excluding src by doing -<src> is not possible since all path exclusions / inclusions are seen as being inside src already.

I’m sure if you would have the structure

src
   source_orig
   source_copy

And would do

src_filter = +<*> -<.git/> -<.svn/> -<example/> -<examples/> -<test/> -<tests/> -<source_orig/>

the filter would work to only compile the source_copy folder.
