Current state of things on Linux / Msys2 and macOS:

• If you are building a project with addons in VS Code or Make you need to manually copy the addon shared libraries to the bin directory ( and on Linux confusingly into bin/libs )
• If you don't you'll get runtime linker errors ( only with addons )

This PR copies addon shared libraries as part of the make command and also changes Linux to look for shared libs in project/bin/ ( mirroring Windows and macOS behavior ).
