In windows HIP SDK can be installed to get HIP include files and it install cmake config files of HIP to fixed path For example latest SDK available on windows is of 5.7 version and it installs it to - C:/Program Files/AMD/ROCm/5.7/lib/cmake/hip So when searching for HIP config files I have added this hardcode path but also gave an option for user to set environment variable HIP_DIR to pick config files from that location.
