fix: ship libcurl.lib in Windows ARM64 C++ kits - #788
Conversation
The packager only globbed vcpkg x64-windows-static, so ARM64 kits shipped http_transport_curl.cpp.obj without libcurl.lib and rcli failed to link (LNK2019 curl_*). Copy arm64-windows-static and build-tree libcurl.lib as well. Co-authored-by: Cursor <cursoragent@cursor.com>
📝 WalkthroughWalkthroughThe Windows packaging script now searches multiple vcpkg roots and triplets, uses a build-tree fallback for ChangesWindows library staging
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The packaging change can still select a libcurl.lib built for the wrong architecture or configuration, and validation may accept the library in an unsupported directory, causing generated Windows kits to fail or behave inconsistently for consumers. These bounded correctness issues should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Mark the applicable Type of Change, record testing status, identify labels, complete the code and documentation checklist, and state whether screenshots are not applicable. Update the test plan after the cpp-desktop-windows-arm64 kit job confirms lib/libcurl.lib is included automatically.

libcurl.libtied to the active architecture and configuration.The build-tree fallback copies the first recursive
libcurl.libmatch. The match can be an x64/ARM64 or Debug/Release artifact for the wrong kit. TheEXISTScheck at Line 294 then accepts that file because it checks only the filename.Filter candidates by the active triplet, architecture, and Release configuration before copying.

Require the documented lib/ path for libcurl.lib.
n.endswith(lib) accepts libcurl.lib from any directory, such as third_party/libcurl.lib. The documented kit contract requires lib/libcurl.lib. A misplaced library can pass validation and still break consumers that use the kit layout.
Normalize the member path and require a /lib/libcurl.lib suffix.
