+Description: Build with liblua5.3-dev
+ In ibus-libpinyin 1.12.0-2 the liblua5.3-dev build dependency was
+ bumped to liblua5.4-dev. Since liblua5.4-0 is not yet in main
+ (<https://launchpad.net/bugs/1910372>), Ubuntu needs to stay with
+ liblua5.3-dev in debian/control for now.
+ .
+ This patch helps configure.ac to recognize lua5.3 as a lua package
+ when building.
