pkg-config: best practice for setting -rpath?

Question

Are there any best practices to set -rpath or libtool's -R based on a pkg-config output? Do I have to resort to a sed trick?

Answer 1

Generally rpath is not portable, that's why pkg-config packages does not have it, because all the libraries are in the default system path. So why would you use rpath in this case?

"because all the libraries are in the default system path" No, pkg-config (together with PKG_CONFIG_PATH) is much more versatile. – Devotional

I understand what you mean, but can you give an example that a pkg-config library have rpath in other directories? – Evade
