Without pkg-config, the downloaded shared libraries are found by the executable due to cargo run sets LD_LIBRARY_PATH https://github.com/rust-lang/cargo/issues/4879

RPATH could be a better way to set default search path for executable, but it will be hard because cargo does not support RPATH. I will add an explanation for it, and merge this PR.
