Should I mark opencv as machine-specific in arago.conf?

This may be more of an RFC as I have some concerns.
I am concerned with this patch as it adds machine-specific
configuration for opencv, but the recipe is not marked as
machine-specific.
Will this pose an issue?
Yeah, I just replied on this part.
Now I understand that if opencv packaging is done well enough, that
we should still be able to build the qtwayland parts of opencv, but
do not install them in the keystone filesystem so that wayland is
not brought in. However, wayland has a dependency on the ddk, which
is not compatible with keystone machines. Thus the opencv build will
be broken for keystone machines.
Any suggestions?
Quick question - where did 3.1 recipe come from and what exactly qtwayland
dependency do?
The 3.1 recipe was created by Hongmei and based on
http://cgit.openembedded.org/cgit.cgi/meta-openembedded/tree/meta-oe/recipes-support/opencv/opencv_2.4.bb?h=master.
Well, not exactly. The original 3.0 recipe that we added to meta-arago was
backported from meta-oe/master as is.
Then, 3.1 update came along and this one is completely custom, as no other
layer has 3.1 and the dependency on qtwayland is also something that we added.
We use the qtwayland component for the GUI in the video analytics demo.
Ok, by the looks of it, enabling WITH_QT option in opencv allows it to work
with QT and open windows in opencv-enabled apps...
