Thanks @Kaonuri for this code!
Translation for non-Korean speakers:
As you have to uncheck the "Virtual Reality Supported” option, openvr dll is not going to be included in your build. You should put it into the YourBuildName_Data/Plugins/ folder.
I wrote a script to do this automatically in the post-build callback, if anyone needs it:
https://gist.github.com/sergiobd/5dcb2fdda182584ddb7b76af138aa249
@Kaonuri, is this code MIT Licensed? If so, would you mind adding a license for it? e.g. https://opensource.org/licenses/MIT
Is there any way to do this on Unity 2021 or later? The openvr_api.dll is not included in the folder structure
Edit: Solved. For anyone facing the same problem, the openvr_api.dll is located under your Unity project folder instead of the Unity Editor installation folder. The path should look something like this "YourProject\Library\PackageCache\com.valvesoftware.unity.openvr...\Runtime\x64\openvr_api.dll"
Replace the 'x64' to 'x86' if your build settings are set to Intel 32-bit.
