QT 5.9 IMX 6 dual plus yocto/openembedded build questions

[Dexter Travis]

I have tried a few different configuration options with qt and still
getting errors.  I did add the qteverywhere demo to my build to make sure
my app was not an issue.

It seems that eglfs_kms plug is not found either.   my usr lib directory
contains the following files that seems like the right thing but perhaps
not?  many other libs also present.
./usr/lib/libQt5EglFsKmsSupport.so.5
./usr/lib/dri/kms_swrast_dri.so
./usr/lib/libQt5EglFsKmsSupport.so.5.9
./usr/lib/libQt5EglFsKmsSupport.so.5.9.2
./usr/lib/qt5/plugins/egldeviceintegrations/libqeglfs-kms-egldevice-integration.so

./usr/lib/dri/etnaviv_dri.so
./usr/lib/libdrm_etnaviv.so.1
./usr/lib/libdrm_etnaviv.so.1.0.0

./usr/lib/dri/imx-drm_dri.so
./usr/lib/libdrm.so.2
./usr/lib/libdrm_etnaviv.so.1
./usr/lib/libdrm.so.2.4.0
./usr/lib/libdrm_etnaviv.so.1.0.0

dmesg | grep etna shows

If i set QT_QPA_EGLFS_INTEGRATION=eglfs_kms_egldevice i get a different
error.

Any additional assistance appreciated.

Thank you,
