There are some changes to the build and runtime configuration compared to previous versions:

• We now use libdw for symbol lookup. Use the WITH_LIBDW cmake option to enable symbol lookup. The dyninst dependency was dropped.
• The WITH_CALLPATH cmake option was renamed to WITH_LIBUNWIND
• The WITH_NVPROF cmake option was renamed to WITH_NVTX
• The nvprof service was renamed to nvtx
