Wow, cool.

Is the copyright/licensing of these packages clear?  In particular, do
all the files within each package have clearly the same license, or a
compatible license?  (I’d expect it to be the case given that SDL is
widespread, but just asking to be sure.)

Are you sure that all these need to be propagated?

(An input typically needs to be propagated if an installed header
#includes a header of that input, or if the .pc file mentions that input
in its ‘Requires:’ field.)

Otherwise looks good to me!
