CMake has a surprising default behavior where looking up a library by multiple names gives the name order higher priority than the directory search order. For example, if your system provides "llvm-config-14" and CMAKE_PREFIX_PATH includes "llvm-config", CMake will always end up choosing the system-provided llvm-config-14. This change add NAMES_PER_DIR to request the more sensible behavior: directory search order has higher priority than name order, so CMAKE_PREFIX_PATH always wins over system-provided tools/libraries.
