[cmake-developers] commit 0e2ed9b09 cause LLVM config step slow

[comicfans44]

Hello everyone, I use cmake(git master) to build llvm source . and found 
this commit

 0e2ed9b097275ce45f61def179b0d3c7d71b83fa
 Merge topic 'linked-usage-cleanup' 

makes cmake config step very slow

re-run cmake to config ,console shows
...
-- Clang version: 3.2
-- Configuring done

 2~3 minutes 

-- Configuring done
-- Generating done
-- Build files have been written to .....

did not see this before (also git master )
previous version 57833095ff1e3d07634472a79348f9dc428c7df2 has no such problem.

hopes this can help improving CMake

thank you.
