I don't really know LLVM's buildsystem, but this looks about right to me.
Sidenote:



================
Comment at: cmake/config-ix.cmake:94
+if (LLVM_ENABLE_LIBPFM)
+  check_library_exists(pfm pfm_initialize "" HAVE_LIBPFM_INITIALIZE)
+  if(HAVE_LIBPFM_INITIALIZE)
----------------
Sidenote: **normally**, this should be in a `cmake/Modules/FindPFM.cmake`, and this should be just
```
if (LLVM_ENABLE_LIBPFM)
  find_package(PFM REQUIRED)
endif()
```
