First of all, thank you for your PR. vue-tsc itself already supports tsc's --project option. Is this PR intended to achieve different behavior from the original --project option?

@johnsoncodehk
Thanks for your reply.
I thought vue-tsc is not supported to set own tsconfig.json path by tsc's --project option.
I write the reason below.

executed vue-tsc@2.0.22

$ npx vue-tsc --noEmit --project ./tsconfig.json ./pages/index.vue
error TS5042: Option 'project' cannot be mixed with source files on a command line.

• index.vue

<script setup lang="ts">
function test(arr: string[]) {
  const a: string = arr[1]
}
</script>

<template>
  <div>
    <button type="button" @click="test([])"></button>
  </div>
</template>

• tsconfig.json

{
	"compilerOptions": {
		"noEmit": true,
		"strict": true,
		"noUncheckedIndexedAccess": true,
	},
	"exclude": ["node_modules"]
}

according to your reply

vue-tsc itself already supports tsc's --project option

It is a bug, isn't it?

I challenged to add code for fixed this problem, but I found this PR is still not enough fixed to this problem.

Oh, sorry.

I found it is a tsc's specification.

I will close this PR and Discussion #4466 .
