Using qttools-5.1.1... In short, Qt5LinguistToolsConfig.cmake ends up defining Qt5::lrelease to point to /usr/lib64/cmake/Qt5LinguistTools/bin/lrelease instead of /usr/lib64/qt5/bin/lrelease It would appear this was supposed to be fixed in 5.1.1, https://bugreports.qt-project.org/browse/QTBUG-32570 but apparently not? -- Rex
