Lyra project - Multiple game targets found for project. can't package/build the game - what do?

Hi there,
Thank you for these detailed steps. I am the final step of generating VS project file, it didn’t open automatically and I didn’t find any errors. Great. I can see more options in VS then before, which proves you were right. Thanks.

My questions for you, @dorusoftware :

  1. Do I need to build all that options for Lyra Multiplayer (debbug, dev, ship - for both client and server)? There are too many builds, I am not sure which one of those are really necessary.
  2. Can I build Lyra Client and EOS from Visual Studio first, or do I need an additional setup in the project editor?

I got this error when trying to build LyraGameEOS in dev win 64:

1>UnrealBuildTool : warning : LyraGameEOS and dynamic target options are disabled when packaging from an installed version of the engine
1>UnrealBuildTool : error : LyraGameEOS modifies the value of CustomConfig. This is not allowed, as LyraGameEOS has build products in common with UnrealGame.
1> Remove the modified setting, change LyraGameEOS to use a unique build environment by setting ‘BuildEnvironment = TargetBuildEnvironment.Unique;’ in the LyraGameEOSTarget constructor, or set bOverrideBuildEnvironment = true to force this setting on.

Any directions? Do I need the Engine built from the source?
Thank you.
