Conan warnings in CI build output

[kyllingstad]

Looks like we need to update our Conan command options. From the build output, step “Build cosim”, line 75 (or thereabout):

conan create \
  --settings="build_type=Debug" \
  --options="proxyfmu=False" \
  --options="shared=False" \
  --update \
  --build=missing \
  --build=b2/* \
  --user=osp \
  --channel="${CHANNEL}" \
  .
WARN: legacy: Unscoped option definition is ambiguous.
Use '&:proxyfmu=False' to refer to the current package.
Use '*:proxyfmu=False' or other pattern if the intent was to apply to dependencies
