that's part of my reasoning, actually. it's pretty hard to tell if a
header 'library' is going to be picked up by other ports in the tree
and how it interacts. and obviously check-lib-depends won't detect
that simde is used if you build another port with it installed..

at least multimedia/vvenc and mozillas have bundled copies, so another
concern is which version gets picked up if a system version is available,
and whether that's compatible with their usage. these incompatibilties
often shows up with other ports like this (xxhash and fmt, while
providing actual libraries too, also provide header-only versions,
and we frequently run into incompatibilities).
