Once the driver project has converted to using cmake that is what I plan to do - use find_path() to look for driver_root/CMakeLists.txt. But in the meantime I'm stuck using find_file() instead which works but it looks like a bug that I need to specify the NO_DEFAULT_PATH option to avoid getting an incorrect match.<br>
