The build scripts will be run before the crate gets compiled. Thanks to the cargo toolchain, we use `cargo:rerun-if-changed=PATH` to enable the build.rs will only run if the files were changed.

Awkward / Redundant Structure:

Inaccurate:
"to enable the build.rs will only run"
Accurate:
"to ensure that build.rs only runs"
(or more simply: "so that build.rs only runs")

Tense Consistency:

Inaccurate:
"if the files were changed"
Accurate:
"if the files have changed"
(or "if the files change" for general present meaning)
