Default [Q]How could use HDR+ as stock 4.4.2 in OMNI or CM11?

I tried http://forum.xda-developers.com/show....php?t=2012857 but still no HDR+ in camera
And I copied the apks and libs from the stock ROM including---
app/GalleryGoogle.apk
app/GoogleCamera.apk
framework/com.google.android.camera2.jar
lib/libgcam.so
lib/libgcam_swig_jni.so
lib/libjni_eglfence.so
lib/libjni_filtershow_filters.so
lib/libjni_mosaic.so
lib/liblightcycle.so
lib/libnativehelper_compat.so
Wipe the dalvik cache,reboot --- not work..

So how could I got the HDR+ Mode in OMNI or CM11? Thanks a lot.
