NOTE：修改qmake.conf文件，要特别注意它的inluce目录、交叉编译器的设置，以及INCDIR和LIBDIR是否正确；

NOTE：对比Qt的mainline里面的qmake.conf，观察它新增的内容；

NOTE：$$QT_INSTALL_DIR/src/3rdparty/powervr/wsegl2这个目录并不存在，但并不影响编译结果；

另外还要将交叉编译器的bin目录加入环境变量PATH，拷贝头文件和lib（为了省事可以把lib的内容全都拷贝进目标文件系统，但是这里还是暂时采取需要什么就拷贝什么的方法，你甚至先什么都不做，等到编译报错的时候再去寻找对应的lib或者头文件，这样能够更加清晰的理解Qt的编译过程），再执行configure和make步骤：

另外，还要将目标文件系统的include/freetypes2/freetype软链接成include/freetype：

[maria@localhost qt-everywhere]$ cd /home/maria/qt/qt-am335x/roofts.withSDK/usr/include

[maria@localhost include]$ ln -s freetype2/freetype freetype

(如果freetypes报错了就做此修改，没有报错的话就不用管了～)
