ci : fix openblas build (#2511)

* ci : fix openblas build

* cont : would this work?

* ci : I'm sorry, windows

* cont : disabled wrong build

* ci : fix openblas build with pkgconfiglite (#2517)

- choco install pkgconfiglite (vcpkg-pkgconf doesn't contain pkg-config executable?)
- vcpkg install openblas (otherwise it is not detected now)
