vcpkg builds every port twice (release + debug) in manifest mode and the VCPKG_BUILD_TYPE environment variable is ignored there; pin the build type in overlay triplets instead (tooling/vcpkg-triplets/release, one per supported triplet). The release configuration is what both workflows consume: FFMPEG_DIR drives the release layout (lib/pkgconfig) and the C ABI is identical for the debug binary CI tests. Verified locally in debian:12: a release-only overlay builds zlib/libpng/openssl/pkgconf/ libsndfile with zero debug trees. Debug-only is not an option: ports like zlib patch files in the release layout and fail when only the debug configuration is built.

vcpkg overlay triplets
Small overlays over vcpkg's builtin triplets, passed to vcpkg install
with --overlay-triplets <dir> (both workflows, see
.github/workflows/ci.yml and .github/workflows/cd.yml).
release/ pins every supported triplet to the release configuration
(set(VCPKG_BUILD_TYPE release)): vcpkg otherwise builds every port
twice — release and debug — which doubles the FFmpeg/port build time in
CI and CD. Our build scripts only ever consume the release layout
(FFMPEG_DIR=<prefix> with <prefix>/lib/pkgconfig, plus the linker
paths those .pc files carry), so the debug half was pure waste; the C
libraries' ABI is identical for the debug cargo binary CI tests.
Notes:
- The non-build-type settings mirror vcpkg's builtin triplets
(
scripts/triplets/) so the overlay stays a drop-in replacement; a vcpkg upgrade that changes a builtin triplet should be mirrored here. VCPKG_BUILD_TYPEmust be set in the triplet: the environment variable of the same name is ignored in manifest mode.- Do not try
debughere: several ports (e.g. zlib) patch files in the release layout and fail when only the debug configuration is built.
