# It then looks in the KDE install directory ($KDEDIR/lib) for libraries with a
# similar name and replaces all occurences of those libraries with a symlink to
# the library in the build directory.
# "Similar name" in this context means the basename of the given library plus any
# suffixes, e.g. ".1.0.0".
