after successfully running make init building the samples fails with the following error:

I've been digging a bit deeper and found that the headers depth_processor.h etc are not included because #ifdef WITH_CAM_MODELS evaluates to false for whatever reason.
After commenting this out and fixing a hand full of include paths (for example in equidistant_camera.h changing "api/camera_models/camera" to just "camera.h") the compilation is now finishing without errors, but the linking fails:

[  1%] Linking CXX executable ../_output/bin/record

ah, and the following quick patch fixes the OpenCV naming issues I also ran into:

Hi this issue caused by Opencv 4.X , please install Opencv 3.X instead.

[nvoelzow]

I'll give that a try - I would suggest to update the SDK to support a recent version of OpenCV, or at least update the docs to assure that the right version of OpenCV is installed (the reference to the installation guide of OpenCV will automatically lead to installing 4.x)

[harjeb]

We‘ll update the doc in next release,Thanks for giving advice

[BernardinD]

Has there been any progress on this? I'm having the same issue

[zhufeng888]

I use opencv-3.4.12 but get the same issue.
