GCC will warn on unused functions, labels, etc. But it seems it doesn't warn on unused definitions? Is there a way to detect unused struct definitions automatically?

You won't necessarily be able to identify individual structs but there is a tool called include-what-you-use which allows you to eliminate unused includes. See here:

and here for using with CMake: How to use the tool include-what-you-use together with CMake to detect unused headers?
