xplatform： 选择交叉编译时的目标 mkspec

prefix ：指定 make install 的位置

./configure -release -opensource -confirm-license -xplatform aarch64-linux-gnu-gcc -prefix /opt/aarch64—qt5 -nomake examples -nomake tools -nomake tests -no-opengl

编译安装Qt5.15.6 过程中遇到的问题处理集
交叉编译带opengl的qt5.12.0（eglfs-mali 、eglfs-x11）
添加QT支持OpenGL es2和eglfs库的路劲和头文件。 确定文件系统中包含opengl的库。可以在文件系统usr目录下找一下libEGL.so libGLESv2.so这两个库

find .| grep "EGL"
find .| grep "GLESv2"

如果没有找到相应的库。可以通过下面命令安装。

sudo apt-get install libgles2-mesa
sudo apt-get install libgles2-mesa-dev
