I’m running into an issue were using the CMake install command to copy a directory with over 5000+ files (slightly over 1GB of data) takes a lot more time than doing a simple copy. On an SSD drive it takes 0.2 seconds to copy, while it takes about 56+ seconds for CMake to do the same thing using the install command. Why is there so much a big difference? 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?
