ci: Match `VCPKG_HOST_TRIPLET` to `VCPKG_TARGET_TRIPLET`
Using a non-default target triplet introduced a regression because
packages with `"host": true` in their vcpkg configurations were still
picking up the default `x64-windows` triplet, effectively building both
release and debug packages.
Fix this regression by setting `VCPKG_HOST_TRIPLET` explicitly.
What changed, and why it matters
This is a routine build-system fix for Bitcoin Core's Windows continuous integration (CI). It tells the vcpkg package manager to use the same release-only build configuration for both host and target packages, avoiding unnecessary debug builds and speeding up CI. There is no security relevance in the commit itself or in the supplied materials.
No security action required. Treat as a normal CI/build optimization change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit adds -DVCPKG_HOST_TRIPLET=x64-windows-release to the CMake generate command in .github/ci-windows.py so it matches the existing -DVCPKG_TARGET_TRIPLET=x64-windows-release. Without this, vcpkg’s host: true dependencies defaulted to x64-windows, which builds both release and debug variants, causing a CI regression (longer builds, not a runtime bug). The change is purely a CI optimization/fix.
