The reason I had this on the list is that in many build systems, these two steps are intimately linked. E.g. in autoconf, "figure out which dependencies I'm going to use" (aka prepare_build_metadata) and "set up an out-of-tree build directory" are the same operation. Alternatively "sniff the system and config files etc. to figure out what what dependencies we're going to use" could be just another build target -- but then it still requires that the build directory be set up first. -n -- Nathaniel J.
