Had similar problem when working with crate opencv, error:

Compiling clang-sys v1.6.1
The following warnings were emitted during compilation:

warning: could not execute `llvm-config` one or more times, if the LLVM_CONFIG_PATH environment variable is set to a full path to valid `llvm-config` executable it will be used to try to find an instance of `libclang` on your system: "couldn't execute `llvm-config --prefix` (path=llvm-config) (error: No such file or directory (os error 2))"

error: failed to run custom build command for `clang-sys v1.6.1`

I'm building on Ubuntu machine so it was solved by installing: apt install libopencv-dev clang libclang-dev
