第一次编译没有遇到这个情况，第二次源码删了重新编译遇到这个情况了
解决： 在源码根目录下创建俩空文件 touch .qmake.stash .qmake.super 该问题即可解决。
配置了交叉编译文件的环境变量（不知道有没有用）
export PATH=/opt/bstos/linux-23/sysroots/x86_64-bstsdk-linux/usr/bin/aarch64-bst-linux:$PATH
备份qmake.conf：

强制添加qglobal.h的头文件路径（核心修复）
INCLUDEPATH += /home/qt-everywhere-src-5.12.8/qtbase/src/corelib/global
INCLUDEPATH += /home/qt-everywhere-src-5.12.8/qtbase/include
INCLUDEPATH += /home/qt-everywhere-src-5.12.8/qtbase/include/QtCore
确保编译器能找到依赖的库路径
LIBS += -L/opt/bstos/linux-23/sysroots/aarch64-bst-linux/usr/lib
