Support building Unity Source Externally to Unity

[andreiborodin]

There was an ask to have the following scenario:

• A Unity project that references an MSBuild project
• The MSBuild project compiles a source file that depends on Unity concept
  • This source file isn't compiled by Unity
• The output of this MSBuild is brought into Unity

Support for this could be as minimum as setting up a proper sample based on existing capabilities, or we can look into doing something more here.

Hacked up sample is #61, request originated in #44.

Thanks for supporting this feature, I have another question:

Do you think is it possible to have a directory next to the asset folder named for example CustomUnityBuild which references UnityEngine or other Unity namespaces?

example:

UnityProject\Assets\ CustomUnityBuild\.src

to ->

UnityProject\CustomUnityBuild

which output the dll in UnityProject\Assets\Plugins\...

Yeah, you should be able to move the project in that example to anywhere under "UnityProject"
