meet a llvm3.8 error when i cmake the project

[sanbuphy]

Hi,I really want to use this software, but I still can't compile it, It always says that "Found LLVM 3.8.0 in /usr/local",but i can't find anything about LLVM 3.8.0 in /usr/local.

Can you help me ? Thanks a lot.

I use:

cmake .. -DLLVM_CONFIG_EXECUTABLE=/usr/bin/llvm-config-7 -DCMAKE_BUILD_TYPE=Release

in build
