No dist folder after pip wheel . --verbose

[Avasam]

Expected behaviour

I was following https://github.com/opencv/opencv-python#manual-builds and it mentions that there should be a dist folder after running pip wheel . --verbose.
Wheel has been created successfully under c:\users\avasam\appdata\local\pip\cache\wheels\36\47\24\1425c4092457ce2b8425961e2805f88bece7c00a1967174324

Actual behaviour

But I don't see any dist folder.

Steps to reproduce

git clone --recursive https://github.com/opencv/opencv-python.git
cd ./opencv-python/
git submodule set-url opencv https://github.com/ddacw/opencv.git
git submodule set-branch -b stub-gen-next opencv
git submodule sync
git submodule update --init --recursive --remote
pip install -U pip
pip wheel . --verbose

Note that I did have to change my opencv-python branch to https://github.com/bertsky/opencv-python/tree/fix-py38-build because of #836

Issue submission checklist

• This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• I'm using the latest version of opencv-python (kindof? see linked issue)
