Adds .github/workflows/bump-viam-cpp-sdk.yml, a daily scheduled workflow that opens a PR bumping the viam-cpp-sdk conan pin whenever a newer SDK release is published. Dependabot has no conan ecosystem, so the bump is done explicitly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The windows-latest image was rolled onto windows-2025-vs2026 (~2026-06-28), which ships Visual Studio 18 "2026". Conan then auto-selects the "Visual Studio 18 2026" CMake generator, but abseil pins cmake<4 (3.31.9), which doesn't recognize that generator and fails to configure. Force abseil onto cmake 4.x (which does), leaving all other dependencies untouched. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

.github/workflows/bump-viam-cpp-sdk.yml— a daily scheduled workflow (plusworkflow_dispatch) that opens/updates a PR bumping theviam-cpp-sdkconan pin inconanfile.pywhenever a newer SDK release is published on viamrobotics/viam-cpp-sdk.Why a custom workflow rather than Dependabot: the SDK is pinned via conan, which Dependabot has no ecosystem for.
conanfile.py.conan.lockvia conan if the repo has one (realsense does; the#recipe-revisionhash means a plain text replace is not enough).GIT_ACCESS_TOKENbot secret (same oneviam-python-sdk'supdate_protosuses) so the bump PR actually triggers CI.Opened as a draft for review.

While opening this PR its
build-module-windowscheck was failing — but not because of anything here. GitHub rolled thewindows-latestimage ontowindows-2025-vs2026(~2026-06-28), which ships Visual Studio 18 "2026". Conan then auto-selects theVisual Studio 18 2026CMake generator, but abseil pinscmake<4(→ cmake 3.31.9), which doesn't know that generator and fails to configure (Could not create named generator). Every dependency that resolved to cmake 4.1.2 (bzip2/c-ares/zlib/zstd) built fine on the same runner.The second commit adds a one-line, abseil-scoped conan override in
build.ymlso abseil builds with cmake 4.x (which understands the new generator); all other deps are untouched. This is bundled here so the PR's own CI can go green.Verified by comparing the passing 2026-06-08 run (image
windows-2025, VS 2022, generatorVisual Studio 17 2022) against the failing 2026-07-02 run (imagewindows-2025-vs2026, VS 18, generatorVisual Studio 18 2026) — identical cmake recipes in both; only the runner's Visual Studio changed.
