We deleted the destination folder every time we did a test. And it's an SSD drive, I don't think having files in cache would be the issue. When files are already there it still takes 30+ seconds for cmake to "not" copy the files.

Is this intended for some reasons or could there be a bug? Thanks! Did you run the manual copy right after the cmake install? (e.g. could files still have been in the system's disk cache?). Both a manual copy and a cmake install might omit copying if the source isn't newer than the destination file; did you perform both with the destination files missing?
