fix: optimize lrelease command with additional flags

The lrelease command in the CMake build process has been enhanced with
additional flags for better performance and output quality. The changes
include adding -compress flag to reduce the size of generated .qm files,
-nounfinished to exclude unfinished translations, and -removeidentical
to remove identical translations. Additionally, a new custom target
'generate_qm' has been added to ensure all .qm files are generated as
part of the build process.

Influence:
1. Verify that .qm files are correctly generated during build
2. Check that translation files are smaller in size due to compression
3. Ensure unfinished translations are properly excluded from final
output
4. Test that identical translations are removed to avoid redundancy
5. Confirm the generate_qm target builds all translation files as
expected

fix: 优化 lrelease 命令并添加额外标志

CMake 构建过程中的 lrelease 命令已通过附加标志进行增强，以提高性
能和输出质量。更改包括添加 -compress 标志以减少生成的 .qm 文件大
小，-nounfinished 以排除未完成的翻译，以及 -removeidentical 以移除相同的
翻译。此外，新增了一个自定义目标 'generate_qm'，以确保所有 .qm 文件作为
构建过程的一部分被生成。

Influence:
1. 验证构建过程中 .qm 文件是否正确生成
2. 检查翻译文件是否因压缩而体积变小
3. 确保未完成的翻译被正确排除在最终输出之外
4. 测试相同的翻译是否被移除以避免冗余
5. 确认 generate_qm 目标按预期构建所有翻译文件
