Skip hidden folders when copying to temp about muter HOT 2 CLOSED

If we don't copy those, won't it either fail to build, or waste time regenerating those items? Can we ignore them from mutation testing, but still copy them?

from muter.

Yes, it will need to regenerate those items.
Copying will make it fail to compile, because the module cache will point to the real path, but it will error out (outside of sandbox probs)

<unknown>:0: error: PCH was compiled with module cache path 
'/Users/rafaelmachado/Projects/muter/.build/x86_64-apple-macosx/debug/ModuleCache/3Q9EPCVIUUF6Y', 
but the path is currently 
'/private/var/folders/xy/2gwd4xw17_x3r_x80n1djh340000gp/T/TemporaryItems/(A Document Being Saved By muter 150)/muter/.build/x86_64-apple-macosx/debug/ModuleCache/3Q9EPCVIUUF6Y'

All the above is for SPM projects tho
