The scons file has the ability to handle multiple paths, although only one is used, etc. In general, scons "takes things literally" and does not handle platform dependencies implicitely (_svn vs. .svn). I think that was a conscious design decision.
I think is is a fair comparison, they are not exactly the same, but
not in any important way from what I can tell.
Ignoring _svn is not common, I found its because of a windows only
When searching for this quite a few links pointed to blender's SCons
files and I didn't find other projects using it.
Nevertheless we could have 'PATTERN _svn EXCLUDE' in cmake too, my
point is that walking the filesystem is overkill when you want to
recursively copy a directory and ignore some files.

Yep, this would be good, I'm not especially fussed if its a class or a
function, some functionality CopyDir(from, to, exclude) should be
used, though I'd have expected scons could already do this.

It shouldn't, its quite strange that it does this, at a guess it could
be because of how scons sets up OSX app bundle.
