AWTK 和 QT 资源占用不完全对比

因为没有开发两个完全一样的应用程序，对比的结果并不是很准确，仅供参考。

对比的程序为：

AWTK demoui 演示了 AWTK 常用功能。
QT QDesktop 演示了 QT 常用功能。

运行平台为： i.MX6ULL Linux

依赖的库比较多，只是看几个基本库

-rwxr-xr-x 1 root root 5.0M Aug 14  2019 /usr/lib/libQt5Gui.so.5.12.9
-rwxr-xr-x 1 root root 5.1M Aug 14  2019 /usr/lib/libQt5Widgets.so.5.12.9
-rwxr-xr-x 1 root root 5.6M Aug 14  2019 /usr/lib/libQt5Core.so.5.12.9

结论：QT 的库和可执行文件比较大，是 AWTK 的 10 倍以上。
