关键摘要:

• 在fix_install.patch中，修改了CMakeLists.txt中的安装目标路径，从${CMAKE_INSTALL_PREFIX}到${CMAKE_INSTALL_PREFIX}/bin，这可能影响应用程序的图标和快捷方式的位置。
• 添加了两个安装目标：Tasker.desktop到share/applications/，clock-256.png到share/icons/hicolor/16x16/。

是否建议立即修改:

• 是，需要确认新的安装路径是否符合预期用途，并且检查新增的安装目标是否与系统规范和用户预期一致。如果这些更改会影响应用程序的可用性和用户体验，应立即审查和修改。
