[13740] Add afunction that checks for repeated -I paths (issue #78)

[juanjo4936]

Description

Added a function that checks if the paths included with the -I function have already been added, and skips them if so. This solves issue #78, and was suggested by the original author. I had to update a couple of terms to the new notation, so we should be careful with backports.

@Mergifyio backport 3.3.x 2.5.x 2.1.x

Fixes #78
