[Bf-committers] CMake cannot find system-wide LLVM installation

[IRIE Shinsuke]

Hi,

I'm using system-wide LLVM installed in /usr on Ubuntu 12.10, but
CMakeLists.txt cannot find it so I have to specify the directory
explicitly by a command line option -DLLVM_DIRECTORY=/usr.

The following patch should fix this bug:
