# NOTE: We assume the user has copied the Windows SDK to ./sdk-win
# In the real build context, we need to make sure this path aligns.
# For now, we assume the build context includes the SDK at services/skp-converter/sdk-win or similar.
# BUT, the SDK is in Documentation/SDK_WIN_x64_2026-1-185.
# We will instruct the user to COPY it or we will reference it if context allows.
# For this Dockerfile, we expect the SDK to be available at build time.
