Qt creator for non qt existing project, include paths

[masa4]

I have a non qt, non cmake project. I imported it to qt creator. It creates some files on top dir: https://doc.qt.io/qtcreator/creator-project-generic.html#specifying-include-paths-and-framework-paths

For making intellisense/code completion work, i need to add header file paths to .includes file. But i have several libraries and pkg-config --cflags somelib outputs lots of paths. And i have to copy them and paste them line by line to .includes file.

Are there any easy way to configure include paths instead copy pasting all paths?
