Where are my project's dlls saved?

I'm looking for the dlls generated by Unity for my code so I can point my editor at them for autocompletion.

I use vim and a linting plugin for it called ale. It instructs you to set a variable to your project's obj/Debug/ folder path:

T$$anonymous$$s variable defines a list of external assembly (*.dll) files required by the mono mcs compiler to generate a valid module target. The list is passed the mcs compiler using the -r: flag.

For example:

 " Compile C# programs with the Unity engine DLL file on Mac.
 let g:ale_cs_mcsc_assemblies = [
 \ '/Applications/Unity/Unity.app/Contents/Frameworks/Managed/UnityEngine.dll',
 \ 'path-to-unityproject/obj/Debug',
 \]

However, my when I checked out my Unity project onto a new computer, it does't have an obj/ folder next to my Assets/ folder.

I've tried Assets > Open C# project.

My Assembly-CSharp.csproj has a line that says <OutputPath>Temp\bin\Debug\</OutputPath> but my project's Temp folder only contains ProcessJobs, UnityLockfile, and two UnityTempFile-* files.
