In order to install QT5 on my Linaro-Ubuntu running on IMX6, I run this command on 5.6 and 5.7..

./configure -opengl es2 -device linux-imx6-g++ -device-option CROSS_COMPILE=/opt/gcc-linaro-4.9-2015.02-3-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot ~/rootfs -prefix /usr/local/qt5 -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5 -v

but, I always face so many errors.  it is one of them but all errors are related with includes

/opt/gcc-linaro-4.9-2015.02-3-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -c -pipe -march=armv7-a -mfpu=neon -DLINUX=1 -DEGL_API_FB=1 -mfloat-abi=hard --sysroot=/home/smart/rootfs -O2 -Wall -W -fPIC -I. -I../../../mkspecs/devices/linux-imx6-g++ -o opengles2.o opengles2.cpp
opengles2.cpp:37:25: fatal error: GLES2/gl2.h: No such file or directory
#include <GLES2/gl2.h>
compilation terminated.
make: *** [opengles2.o] Error 1
OpenGL ES 2.0 disabled.
The OpenGL ES 2.0 functionality test failed!
You might need to modify the include and library search paths by editing

I don't understand why QT5 is so stupid as he doesn't find inc files what are already in his own Src tree.

Do you have any complete guy for installing QT5 into Linaro-Ubuntu? thanks..
