Subject: [PATCH 09/14] fix: pass CMAKE_PREFIX_PATH to cmake to locate cuvis
 library

The cmake step relied on $ENV{PROGRAMFILES} in FindCuvis.cmake to
find the SDK at C:\Program Files\Cuvis\bin. On the current Windows
runner image this expansion may not resolve correctly. Passing
CMAKE_PREFIX_PATH explicitly makes cmake search the SDK bin
directory directly, bypassing the env-var lookup.

Subject: [PATCH 10/14] fix: add cuvis bin to PATH for cmake try_run and use
 python -m pip

- Add C:\Program Files\Cuvis\bin to PATH in cmake step so the
  version-check binary compiled by try_run can load cuvis.dll
- Use python -m pip instead of pip to avoid WinError 5 access
  denied on pip.exe self-upgrade (Python 3.9 on Windows)

Subject: [PATCH 11/14] fix: run full NSIS installer in each build job instead
 of caching installed files

Caching C:\Program Files\Cuvis and restoring it in a downstream job
does not replicate the registry entries and PATH changes the installer
makes, so cmake's try_run version check could not load cuvis.dll.

Instead: setup-windows-deps now only caches the installer zip at a
workspace-relative path (reliable to restore). Each build-and-test-
windows matrix job restores the zip and runs the full NSIS installer,
which sets up the complete system state needed by FindCuvis.cmake.

Keep CMAKE_PREFIX_PATH and PATH additions in the cmake step so the
current session sees the SDK regardless of when the installer's PATH
change propagates.
