Vue 2.7.14 ... migration from Webpack to Vitejs, extend Vue

[SaschaAusUlm]

Hi!

We're trying to convert our application (Vue.js 2.7.14) to Vitejs as preparation for a Vue 3 migration later this summer.
So I migrated and "vite build" works fine.
But when I run the application, I encounter the error that our logging mechanism no longer works.

We do a:

`
declare module 'vue/types/vue' {
export interface Vue {
$log: CubeLogger;
}
}

declare module 'vue/types/options' {
export interface ComponentOptions {
log?: CubeLogger;
}
}
`

with CubeLogger being our specialized logging component. In our main.ts we're then assigning an instance of our logger,
so that "$log" exists on "this". Works with Webpack.

But using Vitejs, "this.$log" is undefined and I am not getting far.

Asked on the Vitejs forum here: vitejs/vite#12508

They said probably an issue with vite-plugin-vue2. Is that scenario supported with the vite-plugin-vue2?

If so, then I will submit a test case, no big deal. Just wanted to ask before. Thanks.
