The libgit2 cmake rules generate a .cmake file that tells people linking to libgit2 how to link. This includes the complete path to each of the libraries that libgit2 links, such as /path/to/sysroot/usr/lib/libssl.so.
The build paths were previously removed with a quick sed, but this breaks builds where those target paths exist on the build host as they get used verbatim. However, all of this linkage is redundant as the library directly links to these libraries. Mark the linkage as private, so the references do not appear in the .cmake files.
