Thank you. What was the thing you mentioned in your comment about it being a system header and transitive not affecting build time once? I’m not sure what transitivity has anything to do with build times, given the inclusion is handled by the preprocessor.

And the preprocessor doesn’t take any time?

@user129393192: in C++, when you don't follow a few restricting rules in regards to header files and includes (they are mentioned in the paper I linked to), you can easily end up with one little change in the wrong header file causing a cascade of files which need to be recompiled and relinked. In a small program, this won't matter, but in a program with >1000 classes (each one with a header and a cpp file) this can cause build timesof several minutes, if not hours.
