Don't add c-ares/CMakeFiles dir to exclusion list if doesn't exist #4

Closed yim-lee closed 2 years ago

yim-lee commented 2 years ago

Motivation: c-ares/CMakeFiles/ doesn't exist unless cmake is run locally. User reports that the exclude line causes SwiftPM warning about invalid exclude.

Modification: Add c-ares/CMakeFiles/ to exclude list iff it exists and is non-empty.
