下载 Qt Creator 源码

Github: https://github.com/qt/qttools
笔记打算用 Qt 5.12.12 来编译 qt creator-linguist
所以笔者下载的是 tag - 5.12.12 ，解压后如下，先删除多余的文件，后续还要删除更多文件方便清晰的查看源码.

添加 header.pri

##指定 QtUiTools/private 所在目录.
INCLUDEPATH += D:/Qt/5.12.12/5.12.12/msvc2017_64/include/QtUiTools

手动翻译多语言

在 .pro 中增加多语言, 在 Qt Creator 生成

更新翻译: 更新.ts 文件
发布翻译: 把 .ts 文件生成 .qm 文件，最终利用 QTranslator 类完成界面上显示的翻译.
