Reason

Since we used the llvm installed in our home directory (LLVM - installation), we need to specify the compiler and the path for this llvm.

A better way is to use export as Cmake > Specify compiler shows. However, here we modify the CMakeLists.txt.

Issue

Use absolute path

When specify the path for compiler and llvm-config, we need to use absolute path /home/xinyi.., or it cannot find the path. The reason see CMake -- path.
