说明：
1, xcb是qt和x11交互的主键，debian10默认是没有集成这个组件的，可以用qt自带的xcb组件：qt-xcb。
1, 配置好这个后，还会报一些连接出错的日志。需要配置-c++std c++11 。加上这个配置后，会解决一些编译链接的问题。
相关工具安装
#下面是opengl、xcb相关需要安装的库
sudo apt-get install libx11-dev libx11-xcb-dev #xcb的头文件依赖
sudo apt-get install libxkbcommon-dev libxkbcommon-x11-dev #xkbcommon依赖
sudo apt-get install libxext-dev libxfixes-dev #EGLFS X11的依赖
sudo apt-get install libfontconfig1-dev #QT中-fontconfig选项的依赖
sudo apt-get install sqlite3 libsqlite3-dev #解决qt中配置系统数据库的依赖问题，对应-sqlite选项
sudo apt-get install libts-dev #解决tslib依赖 对应-tslib选项。
sudo apt-get install libjpeg-dev #-system-jpeg 选项
sudo apt-get install libglib2.0-dev #-glib 选项
sudo apt-get install sqlite3 libsqlite3-dev #解决sqlite依赖
sudo apt-get install rsyslog #-syslog选项
qt主机环境配置
export QTDIR=/home/linaro/out
export PATH=$QTDIR/bin:$PATH
export MANPATH=$QTDIR/man:$MANPATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export QT_QPA_PLATFORM=xcb
说明：
这里可以配置QPA平台有：xcb eglfs。但是eglfs平台是全屏的平台。
如果要配置eglfs，好像还需要配置宽高。
附录：编译报错-需要配置-c++std c++11可解决 。导致这个问题还可能原因是板子内存不够。链接库后报失败了。

附录：harfbuzz=qt这个选项也会使得qt编译报错。报错和没加-qt-xcb一样。添加这个，好像因为内存不够大，所以导致编译时，链接失败了。再次编译，报QXcbKeyboard错误了。
