Is there an existing issue for this feature request?

I have searched the existing issues

As a developer it is helpful if i see my own compiler warnings as i introduce them.
Unfortunately there are too many to spot my own mistakes.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

Fix low hanging fruits in src/.
Add SYSTEM to target_include_directories() where 3rd party include directories are added. This reduces compiler warnings we can not do anything about. From the CMake documentation:
[...] If `SYSTEM` is specified, the compiler will be told the directories are meant as system include directories on some platforms. This may have effects such as suppressing warnings or skipping the contained headers in dependency calculations [...]
