Yup, I need to build the package from source code.

From the point of now, I have to cross compile via qemu+chroot. :-(
And, I mentioned earlier, rockchip SoCs can't support OpenGL desktop
feature, so we have to revert
commit(d35641e169dd5a2db4886f83a1bb558a958e3f68), is possible that the
latest qtbase5-dev:arm64 support opengl es?
Dmitry (CCed) is working on that in experimental.
