Build for jetson tx2nx

[AlfredNG]

I cross compile qt5.12.8. Here is the config

./configure -v \
-nomake tests \

My qmake.conf is

# When configured with -opengl es2, eglfs will be functional with its
# dummy fullscreen X11 backend, in addition to xcb.
EGLFS_DEVICE_INTEGRATION = eglfs_kms_egldevice
#EGLFS_DEVICE_INTEGRATION = eglfs_x11

include(../common/linux_arm_device_post.conf)
load(qt_config)

I want to us eglfs.
I found that if I close -eglfs, config is ok, opengl is opened. But EGL---no If I turn on -eglfs. It will show the error

ERROR: Feature 'eglfs' was enabled, but the pre-condition '!config.android && !config.darwin && !config.win32 && features.egl' failed.

Any suggestions？
