Hm. `CMAKE_CURRENT_BINARY_DIR` points to the current binary directory in the build tree. You are setting relative path which points to where? Does it point to another binary directory in the build tree previously create by the build process and containing generated files? or it points to the source directory in the llvm source tree? If the later that's a problem as you accounted on your custom location of the binary tree.
