Just adding a second use-case.

Emacs with cmake-ide (using flycheck) shows warnings that update as you type.
They are generated by running the file through gcc, which could be a .hpp file.
This usually works well enough for interactive use. But it leaves you with an
irrelevant "#pragma once in main file" warning in the editor.

(Not sure if this whole setup is "legit", or if there are better alternatives.
It involves guessing which compile flags of some .cpp file belong to the .hpp
file being edited.)
