I am not sure whether or not I have learnt this grammar before. I am reading a
book about OpenCV and found a sentence as follows.

> OpenCVを効果的に用いるのに必要となるコンピュータビジョンについての一般的な背景知識もあわせて説明します。

The confusing part is the grammar

```

    N1+に必要となる+N2
    
```

where

```

    N1=OpenCVを効果的に用いるの
    
```

and

```

    N2=コンピュータビジョンについての一般的な背景知識
    
```

I know

  * `N1をN2とする` that means let N1 be N2.
  * `NをNa-adjにする` or `Nをi-adj-stemくする` that means making N a condition represented by the adjective.

Is it possible to say the following?

> OpenCVを効果的に用いるのに必要と **する** コンピュータビジョンについての一般的な背景知識

How to parse the following "N1+に必要となる＋N2"?
> 「Noun 1 + に必要{ひつよう}となる + Noun 2」

can only mean:

> "Noun **2** (which is) necessary/required for Noun **1** "

because「Noun 1 + に必要となる」 functions as a relative clause modifying 「Noun 2」. In
other words, **between Noun 1 and Noun 2, the latter is the "main" noun of the
whole phrase**.

Thus,

> 「OpenCVを効果的{こうかてき}に用{もち}いるの **に必要となる** コンピュータビジョン」

means:

> "the computer vision (technology) necessary/required for effectively
> utilizing OpenCV"

For those who are wondering, the 「の」 in 「用いるの」 is a nominalizer, making it
possible to treat the phrase 「OpenCVを効果的に用いるの」 just like a noun. That whole
phrase is what the questioner is calling "N1".

Finally,

> Is it possible to say the following?
>
> OpenCVを効果的に用いるのに必要と **する** コンピュータビジョン

No, it is not possible. 「なる」 and 「する」 mean very different things; therefore,
they cannot be used interchangeably. I could not think of an exception.
