Public bug reported:
When building project with llvm-libs using cmake, cmake is complaining about
incorrect library path. It looks like installation path is incorrectly setup.
Also, 3.7 doesn't have any problem.
DISCLAIMER: I'm using ubuntu docker, don't know if that changes anything.

Expected output(something like below), also I can confirm that it can work once
all the path and symlink in the files are fixed:

Attachment is a dummy project file that uses llvm and clang, need package:
llvm llvm-dev clang libclang-dev
To reproduce the error
1. unarchive
2. cd
3. mkdir build
4. cd build
5. cmake ..
** Affects: llvm-toolchain-3.8 (Ubuntu)
