I suggest to check version from `cp --version`, simply looking for "--reflink" in the help introduces the risk of matching version having "--reflink" but not "--reflink=auto". I'm very new to CMake code base, what is the most appropriate location for a check like this? BTW: I've been told that in future reflinks and server-side copies (useful for network file systems such as NFS and Samba) will be handled in a single way at VFS level. If such an API emerges we can think to integrate it, but for now `cp --reflink` is for sure the simplest and most future-proof solution. -- Ale -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
