When renaming a project in the Projucer, everything that was originally named after the project name (when the project was first created) should also be changed.
If I create a plugin project called ‘ABC’, the project name, the plugin name, the VS binary names, etc. are all named ‘ABC’. However if I then rename my project to ‘XYZ’ most of the other options stay as ‘ABC’.
I was getting linker errors in VS looking for a .lib file named after my old project name and it took me a while to find where the setting to change the binary name was in the Projucer. Not an error, just a little irritating!
