+When building HIP, you will likely want to build and install to a local user-accessible directory (rather than <ROCM_PATH>).
 This can be easily be done by setting the -DCMAKE_INSTALL_PREFIX variable when running cmake.  Typical use case is to
 set CMAKE_INSTALL_PREFIX to your HIP git root, and then ensure HIP_PATH points to this directory.   For example
