Qt CMake创建qm文件

Question

我在创建/更新qt翻译文件(ts->qm)时遇到了一些问题。

谈到CMake，我绝对是个菜鸟。为了解决这个问题，我已经在google上搜索过了，但是它根本不起作用，而且还有另外一个问题: CMake删除.ts文件，我需要一次又一次地从备份中复制它们。这是真正的阿诺伊。无论如何，这里是我的CMake文件：

cmake_minimum_required(VERSION 3.12)

project(MarkdownEdit VERSION 1.2.0 LANGUAGES CXX C)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

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

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

如果我们能解决这个问题，我会很高兴的。提前谢谢，祝您今天愉快。

还有一个问题: CMake删除.ts文件，我需要一次又一次地从备份中复制它们。这是真正的阿诺伊。

您使用哪种版本的QT？Qt有5.15.6和6.2版本的臭虫：TS文件在清理时被删除。它已在Qt 5.15.9和6.3中固定。
