 # Check for libpfm.
-check_library_exists(pfm pfm_initialize "" HAVE_LIBPFM_INITIALIZE)
-if(HAVE_LIBPFM_INITIALIZE)
-  check_include_file(perfmon/perf_event.h HAVE_PERFMON_PERF_EVENT_H)
-  check_include_file(perfmon/pfmlib.h HAVE_PERFMON_PFMLIB_H)
-  check_include_file(perfmon/pfmlib_perf_event.h HAVE_PERFMON_PFMLIB_PERF_EVENT_H)
-  if(HAVE_PERFMON_PERF_EVENT_H AND HAVE_PERFMON_PFMLIB_H AND HAVE_PERFMON_PFMLIB_PERF_EVENT_H)
-    set(HAVE_LIBPFM 1)
+if (LLVM_ENABLE_LIBPFM)
+  check_library_exists(pfm pfm_initialize "" HAVE_LIBPFM_INITIALIZE)
----------------
One more piece is missing, `LLVM_ENABLE_LIBPFM` needs to be checked where linking to pfm happens.
