Hi folks,

I have built an updated release of libvpx with the CVE fixes included.
This is a Google WebM project which does not use autotools or libtool, so the last maintainer did their own cygvpx dll build and relinked the executables.

Taking a brief look over the cygport, if you're going to abstract out the soversion, you can use 'declare' to evaluate variable names

e.g.

ABI=8
PKG_NAMES="... libvpx${ABI} ..."
declare libvpx${ABI}_SUMMARY="$SUMMARY (runtime)"
declare libvpx${ABI}_CONTENTS="usr/bin/cygvpx-${ABI}.dll"

The current test programs do not relink against the unstripped dll, possibly because of their sizes requiring > 32 bit offsets, so I am no longer relinking the test programs with the dll, only the distributed utilities.

With codec performance tests disabled, this build also downloads 1.4GB of test data files from Google under:

https://storage.googleapis.com/downloads.webmproject.org/test_data/libvpx/

which we presumably would prefer not to include in the src package, to

Yeah, including it seems a bad idea.

run tests which take 2.75-3.5 hours out of a 3.75-4.5 hour build, with 5 failures in scallywag CI and 2 failures locally out of 1596 tests, shown in the attached log, so I have questions into the upstream WebM libvpx project about those.

Full scallywag logs are available at:

Thanks.

I've added this to your packages.
