The CMake build had the version hard-coded as 5.7.4, while the qmake build read it from compile_version_string.txt (5.8.17-release). The stale number also made the version check report an update. As in the qmake build, the full string becomes APPLICATION_VERSION and its numeric part the project version. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
