define Package/libyang-legacy/description
  libyang-legacy ships the libyang 3.x runtime (libyang.so.3) for binaries
  still linked against the legacy ABI. It is install-time co-installable
  with libyang 5.x (libyang.so.5), whose SONAME differs.

  Build-time consumers should point CMAKE_PREFIX_PATH (or PKG_CONFIG_PATH)
  at $$$$(STAGING_DIR)/usr/lib/libyang-legacy so that the legacy headers,
  library and pkg-config file are picked up in preference to libyang 5.x.

# Staged under a self-contained /usr/lib/libyang-legacy prefix, with a
# sysroot-relative .pc prefix so pkg-config does not double-prepend.
