This is a patch release of 3.4.1 that corrects the patch applied to ipopt.pc files, allowing CyIpopt to be built with the Ipopt libraries included. In addition to removing the Requires.private line in the .pc file (as done in 3.4.1), this release uses relative paths rather than absolute paths in the .pc file.
This release copies binaries from the 3.4.0 release rather than re-building them, and is therefore not in sync with this repository's main branch.
