/*
 * Smoke test for the installed package. See CMakeLists.txt beside this file.
 *
 * Deliberately touches one function from each translation unit -- the version
 * entry points, a string buffer, a formatted append and a print -- so that a
 * library installed with a source file missing from its link line fails here
 * rather than in whatever consumer discovers it next.
 *
 * Returns a distinct status per step, so a CI failure names the step.
