在使用cmake构建一些复杂的qt应用时，因为Qt6组件分散在/usr和/runtime中，需要手动指定它们的位置，不然总是有一些找不到，现在总结如下。

使用方法：将下面的内容复制到 build_env_qt6.sh文件，添加执行权限，构建之前，执行 source build_env_qt6.sh。

我的使用环境：

base: org.deepin.base/25.2.2
runtime: org.deepin.runtime.webengine/25.2.2

#!/bin/bash

## file: build_env_qt6.sh ##

# 获取环境变量
INSTALL_ROOT="/opt/apps/${LINGLONG_APPID}/files"
TRIPLET=$(cat "/etc/linglong-triplet-list" | xargs)

# 定义Qt6组件搜索根目录
RUNTIME_BASE="/runtime/lib/${TRIPLET}/cmake"
SYS_BASE="/usr/lib/${TRIPLET}/cmake"

# 区分 /runtime (runtime组件) 与 /usr (base组件)
