How to build libobs as dependency of obs-studio-node module?

I am trying obs-studio-node.
This module require libobs as dependency. While building this module it download a pre-built version of libobs if none is specified. We can specify out custom libobs as mentioned in README.md

I followed these steps to build libobs. These steps are listed in README.md

1. git clone https://github.com/stream-labs/obs-studio
2. cd obs-studio
3. git submodule update --init --recursive
4. mkdir build
5. cd build
6. cmake .. -DENABLE_UI=false -DDepsPath="C:\Users\alokm\Downloads\dependencies2019\win64" -DENABLE_SCRIPTING=false -G"Visual Studio 16 2019" -A x64
7. cmake --build .
8. cpack -G ZIP

Last step (cpack -G ZIP) is failing with errors

PS C:\Users\alokm\tmp\streamlabs\obs-studio\build> cpack -G ZIP

CPack Error: Error when generating package: OBS Studio (64bit)

I guess obs-studio does not support cpack so its failing.
How can I build my custom libobs for obs-studio-node mobule?

Check what exact configuration you have built. The output of CPack tries to install the Release configuration. However, you didn't mention any when did project configuration (and it may project-dependent to set some defaults).

Try add explicitly what you want:

$ cmake .. -DENABLE_UI=false -DDepsPath="C:\Users\alokm\Downloads\dependencies2019\win64" -DENABLE_SCRIPTING=false -DCMAKE_CONFIGURATION_TYPES=Release -G "Visual Studio 16 2019" -A x64
$ cmake --build . --config Release
