[SOLVED] qt_create_translation doesn't change .ts file or create .qm file

Issue

I created a small test project to show my problem:

main.cpp

#include <QApplication>
#include <QPushButton>

int main(int argc, char* argv[]) {
    QApplication a(argc, argv);
    QPushButton button(QApplication::tr("Hello, World!"), nullptr);
    button.resize(200, 100);
    button.show();
    return QApplication::exec();
}

CMakeLists.txt

cmake_minimum_required(VERSION 3.27)
set(CMAKE_CXX_STANDARD 23)

project(TestQtWidgetsProject)

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

add_executable(TestQtWidgetsProject main.cpp)

find_package(Qt6 REQUIRED COMPONENTS Core Gui Widgets)
target_link_libraries(TestQtWidgetsProject Qt::Core Qt::Gui Qt::Widgets)

find_package(Qt6 REQUIRED LinguistTools)
qt_create_translation(QM_FILES ${PROJECT_SOURCE_DIR} ${PROJECT_SOURCE_DIR}/translation_ru.ts)

I also created an empty file translation_ru.ts in the project root directory.

But after building the project the file translation_ru.ts remains empty and no .qm file is created in ${CMAKE_BINARY_DIR}. Why?

Solution

I still haven't figured out why this code doesn't work, but as Alan Birtles said, the command is deprecated, so that might be the reason.

Here is a working code example for this project:

find_package(Qt6 REQUIRED LinguistTools)

qt_add_translations(TestQtWidgetsProject
        INCLUDE_DIRECTORIES
            ${PROJECT_SOURCE_DIR}
        TS_FILES
            translation_ru.ts)

add_dependencies(TestQtWidgetsProject update_translations)
