OpenCV Aruco not compiling

Question

Trying to compile opencv-3.4.1 with opencv_contrib-3.4.1 in Visual Studio 15 and I'm getting the following error.

CMAKE

I get that 'CV_OVERRIDE' doesn't exist. But I'm not sure why.

I can compile OpenCV 3.4.1 successfully on it's own. But not with the contrib. Is it just a version mismatch, or am I missing something.

Edit

I have again downloaded 3.4.1, I discover aruco is included in the standard bundle source. But not the preconfigured build. When trying to build it, I get the same errors.

Nothing on google, please tell me I've missed something basic...

Did you compile OpenCV 3.4.1 with EXTRA_MODULE_PATH set to opencv-contrib 3.4.1 using CMake? Because opencv/aruco is included in contrib-module since 3.0. I'm using OpenCV 3.3.1 and I could build it successfully.

Or, alternatively, you could download stand alone aruco 3.0.10 from source and build from binary.

I worked out why it wasn't working. I just havn't posted the it because I have to look up what the module was again. Basically the latest version needs to be compiled on Windows 10, without an additional pack installed. That's why older versions compiled on the same system (Win7). I just gave up and used my laptop that has Win10 installed. – Bradmage Jul 12 '18 at 09:53
@Bradmage Great! You can write your own answer below and mark this question answered, so that people don't need to bother reading each comment. – samliu Jul 12 '18 at 11:59
Of course! Just have to dig through my source comments, don't want to post half information :) – Bradmage Jul 12 '18 at 12:39
