If you have a question rather than reporting a bug please go to https://forum.opencv.org where you get much faster responses.

This is a template helping you to create an issue which can be processed as quickly as possible. This is the bug reporting section for the OpenCV library.

##### System information (version)

<!-- Example

- OpenCV => 4.2

- Operating System / Platform => Windows 64 Bit

- Compiler => Visual Studio 2017

-->

- OpenCV => :grey_question:

- Operating System / Platform => :grey_question:

- Compiler => :grey_question:

##### Detailed description

<!-- your description -->

在vender下面以及build下面的json文件中增加了opencv的节点，文件编译成功，但最终并未在out目录下生成.so文件

out目录下仅有以下几个关于opencv的目录

./build_configs/opencv

./build_configs/opencv/opencv

./build_configs/thirdparty/opencv

./build_configs/mini_adapter/opencv.json

且.json文件内并没有内容

{

"parts": [

"opencv"

]

}

##### Steps to reproduce

<!-- to add code example fence it with triple backticks and optional file extension

```.cpp

// C++ code example

```

or attach as .txt or .zip file

-->

##### Issue submission checklist

<!--

OpenCV team works with forum.opencv.org, Stack Overflow and other communities

to discuss problems. Tickets with question without real issue statement will be

closed.

-->

- [ ] I checked the problem with documentation, FAQ, open issues,

forum.opencv.org, Stack Overflow, etc and have not found solution

<!--

Places to check:

* OpenCV documentation: https://docs.opencv.org

* FAQ page: https://github.com/opencv/opencv/wiki/FAQ

* OpenCV forum: https://forum.opencv.org

* OpenCV issue tracker: https://github.com/opencv/opencv/issues?q=is%3Aissue

* Stack Overflow branch: https://stackoverflow.com/questions/tagged/opencv

-->

- [ ] I updated to latest OpenCV version and the issue is still there

<!--

master branch for OpenCV 4.x and 3.4 branch for OpenCV 3.x releases.

OpenCV team supports only latest release for each branch.

The ticket is closed, if the problem is not reproduced with modern version.

-->

- [ ] There is reproducer code and related data files: videos, images, onnx, etc

<!--

The best reproducer -- test case for OpenCV that we can add to the library.

Recommendations for media files and binary files:

* Try to reproduce the issue with images and videos in opencv_extra repository

to reduce attachment size

* Use PNG for images, if you report some CV related bug, but not image reader

issue

* Attach the image as archive to the ticket, if you report some reader issue.

Image hosting services compress images and it breaks the repro code.

* Provide ONNX file for some public model or ONNX file with with random weights,

if you report ONNX parsing or handling issue. Architecture details diagram

from netron tool can be very useful too. See https://lutzroeder.github.io/netron/
