How can I get a project's executable file from another project within the same workspace?

[GasimGasimzada]

I have two projects in the same workspace:

project "Runtime"
  kind "ConsoleApp"
  basedir "../workspace/runtime"
  -- Other stuff

project "Editor"
  kind "ConsoleApp"
  basedir "../workspace/editor"
  -- Otherstuff

For the example above, I need a way to use the output target of "Runtime" in the "Editor". I either want to copy it to "Editor"'s target output (using postbuildscripts) or automatically set it as a preprocessor definition. I want this to happen at toolchain level and automatically. If I change Runtime's base directory to another place, it should immediately update the paths on next build. I want this to be platform independent as well (on Windows, it should provide the ".exe" or ".dll" while on Linux/macOS it provides executable or ".so" files)

How can I reference or achieve this?
