Building later Opencv versions in Yocto

I am following the NXP eIQ direction to build some machine learning based platforms based on IMX8M.

The Linux 4.14.98_2.0.0 Yocto build just fine and works. My issues is it looks to build and include OpenCV 4.0.1.

I would like to use a later version (4.1.0 or 4.2) as I need an API not included with 4.0.1.

I tried just changing from:

 

PREFERRED_VERSION_opencv = "4.0.1%"

to:

 

PREFERRED_VERSION_opencv = "4.1.0%"

in the local.conf file but it still looks to be building 4.0.1 and it eventually fails.

 

Is it possible to include a later version of OpenCV?
